[android help] Add a number and a Text Input value with adobe flex

You should use String(int i)

lblAnswer.text = String(bloodglucose + 100);

Update: What about something like this:

var i:int = bloodglucose + 100;
var s:String = String(i);
lblAnswer.text = s;

[android help] Streaming Microphone Audio from Android Device to Server over 3G

I am trying to develop a simple Android application that can record audio from the microphone, then stream that data to a server for playback. The solution needs to run on Gingerbread and later and has to work over 3G (so no wi-fi only methods).

So far I have Googled for sample applications that can get me this functionality and come up empty-handed. Most tutorials assume streaming from the server or PC to a device, this is the opposite of what I am trying to accomplish.

Can anyone give me sample code for an app that records mic audio, streams it to a simple server app, and does it all in a way that minimizes audio gaps, delay, and other audio transmission issues?

Edit-- Things I have tried so far: SIP (stack not enabled on some phones, no free SIP stack for commercial use), AudioRecord (don't know how to compress audio), MediaRecorder (can never seem to connect to the remote port), and straight socket programming (very poor sound quality). I'd love to make any of these methods work... maybe I am missing something. Is there a "best practices" way for Android to server audio streaming? I will post the complete code solution when I solve this problem :-)

[android help] A simple Real-Time Mic Meter in Android

I have helped from the book Pro Android media...

Here is the code:

public class MicMeter extends Activity implements OnClickListener {


RecordAudio recordTask;
int blocksize = 256;
int frequency = 8000;
int channelConfig = AudioFormat.CHANNEL_CONFIGURATION_MONO;
int audioEncoding = AudioFormat.ENCODING_PCM_16BIT;
TextView txt;
Button start;
boolean started = false;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_mic_meter);
    start = (Button)findViewById(R.id.button1);
    txt = (TextView)findViewById(R.id.textView1);

    start.setOnClickListener(this);


}


private class RecordAudio extends AsyncTask {

    @Override
    protected Void doInBackground(Void... params) {
        try{
        int bufferSize = AudioRecord.getMinBufferSize(frequency,channelConfig,audioEncoding);
        AudioRecord audioRecord = new AudioRecord( MediaRecorder.AudioSource.MIC, frequency, channelConfig, audioEncoding, bufferSize);

        short[] buffer = new short[blocksize];
        double[] meter = new double[blocksize];

        audioRecord.startRecording();

        while(started){
            int bufferReadResult = audioRecord.read(buffer, 0, blocksize);

            for (int i = 0; i < blocksize && i < bufferReadResult; i++) { 
                meter[i] = (double) buffer[i] / 32768.0; // signed 16 bit
            }
            publishProgress(meter);
        }
        audioRecord.stop();

    }catch (Throwable t) {
        Log.e("AudioRecord","RecordingFail");
    }

        return null;
    }

    @Override
    protected void onProgressUpdate(double[]... meter) {

        for(int i = 0 ; i < meter[0].length ; i++){
            double helper = i;
            txt.setText(Double.toString(helper));
        }

    }


}


@Override
public void onClick(View v) {
    // TODO Auto-generated method stub

    if(started){
        recordTask.cancel(true);
    }else{
        started = true;
        recordTask = new RecordAudio();
        recordTask.execute();

    }
}

}

while i press the button. It shows 255.0 and then it doesn't response... Are there any way to fix it?? Are there any beter version about this?

[android help] android tutorials screen

I was really confused about this topic, so I had to ask. Being new on Android, I was thinking of creating an introductory sort of tutorial like page for the app I am working on, like the one's you see on various apps that is used for the first time in which they point out various features of the app, what functionality does this button perform when pressed, what does the menu item do, in a sort of a dynamic way. What are these actually ?? Are they splash screens? Or are they something really different? asked 8 mins ago

Know someone who can answer? Share a link to this question via email, Google+, Twitter, or Facebook.

[android help] Scrolling over large canvas

I need some help understanding the fundamentals of scrolling over items that are drawn to a canvas in Android. Suppose I want to create a timeline where time at 0 is the top of a visualization and as time increased the timeline continues to be rendered below the previous point. If I wish to render this on Android I know I could simply create a bunch of items on a canvas by overriding onDraw(). However, let's suppose the visualization is bigger than the screen allows.

For example in the first picture below the large black box contains the entire canvas as I render it. I create a blue line that runs vertically up and down as well as several yellow, green and blue rectangles. The red box represents the screen of the Android that is rendering the visualization. As it initially opens all items are drawn but only the items contained within the red box show up on the screen.

Now if the user is to scroll down, items that initially appeared below the red box are in view while items that have gone out of the confines of the red box are no longer visable, as represented in the second picture.

I believe I need to use scrollables but I'm quite lost how to do so. I've read over this page http://developer.android.com/training/custom-views/custom-drawing.html explaining how to create your own customer images and this page http://developer.android.com/training/custom-views/making-interactive.html explaining how to make the UI interactive, but I think I'm missing something.

A sample code that illustrates this problem (this is basic, assume there is logic dictating WHERE the boxes/lines go, etc.) is as follows:

package com.example.scrolltest;

import com.example.scrolltest.Draw;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Color;

public class MainActivity extends Activity {
    Draw draw;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    draw = new Draw(this);
    draw.setBackgroundColor(Color.WHITE);
    setContentView(draw);
    }
}

and

package com.example.scrolltest;


import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;


public class Draw extends View {
    Paint paint = new Paint();

    public Draw(Context context) {
        super(context);            
    }

    @Override
    public void onDraw(Canvas canvas) {

        paint.setColor(Color.GREEN);
        canvas.drawRect(30, 30, 90, 200, paint);
        paint.setColor(Color.BLUE);

        canvas.drawLine(100, 20, 100, 1900, paint);

        paint.setColor(Color.GREEN);
        canvas.drawRect(200, 2000, 400, 3000, paint);
        }
}

[android help] How can i set Wallpaper in android using coding?

I am developing an application that shows the different photos from server and user can set selected photos as wallpaper of its device i used given code to set wallpaper it working but image was not set properly it not fit to screen. I used this code. String dirPath = getFilesDir().toString(); String folder = mPhotos.get(nextPosition - 1).getCategory(); String filePath = dirPath + "/PhotoViewer/" + folder + "/" + mPhotos.get(nextPosition - 1).getFileName(); File imageFile = new File(filePath); Bitmap bitmap = BitmapFactory.decodeFile(imageFile .getAbsolutePath()); WallpaperManager myWallpaperManager = WallpaperManager .getInstance(getApplicationContext()); try { myWallpaperManager.setBitmap(bitmap); Toast.makeText(PhotoActivity.this, "Wallpaper set", Toast.LENGTH_SHORT).show(); } catch (IOException e) { Toast.makeText(PhotoActivity.this, "Error setting wallpaper", Toast.LENGTH_SHORT).show(); } Please help me out. asked 7 mins ago

You can try resizing your bitmap like this DisplayMetrics displayMetrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(displayMetrics); int height = displayMetrics.heightPixels; int width = displayMetrics.widthPixels << 1; // best wallpaper width is twice screen width // First decode with inJustDecodeBounds=true to check dimensions final BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeFile(path, options); // Calculate inSampleSize options.inSampleSize = calculateInSampleSize(options, width, height); // Decode bitmap with inSampleSize set options.inJustDecodeBounds = false; Bitmap decodedSampleBitmap = BitmapFactory.decodeFile(path, options); WallpaperManager wm = WallpaperManager.getInstance(this); try { wm.setBitmap(decodedSampleBitmap); } catch (IOException e) { Log.e(TAG, "Cannot set image as wallpaper", e); } answered 1 min ago

To set wallpaper in android use below code: By using WallpaperManager Class Button buttonSetWallpaper = (Button)findViewById(R.id.set); ImageView imagePreview = (ImageView)findViewById(R.id.preview); imagePreview.setImageResource(R.drawable.five); buttonSetWallpaper.setOnClickListener(new Button.OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext()); try { myWallpaperManager.setResource(R.drawable.five); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }}); Need to set permission in Manifest: answered 6 secs ago

[android help] Google Play - Can I charge for push notifications?

	I am certainly not a lawyer, but I am pretty sure, that you can't monetize content from a website without their permission. Also this site is not for law-specific questions. – Ahmad 4 mins ago
	I don't see why you shouldn't be able to, but as a consumer, I would discard your app pretty quickly. If you're charging me money to enable me to make a purchase later, you're just greedy. I doubt you'll make the money back you'll spend implementing that "feature". – 323go 1 min ago

[android help] Activity Start slowly

Recently I met a strange problem,I start a activity from a service,but if I follow the steps : enter a app press home key to go back launcher then trigger the service to start my activity after above steps,the activity starts more slowly than normal way.Because I add a log in Activity's onCreate method. normal way is same as above,except pressing home key. Please help me solve it.Thanks. asked 16 mins ago

You can run the service and activity in different processes. Use the process attribute for service in AndroidManifest.xml Here's a snippit from the docs: The name of the process where the service is to run. Normally, all components of an application run in the default process created for the application. It has the same name as the application package. The element's process attribute can set a different default for all components. But component can override the default with its own process attribute, allowing you to spread your application across multiple processes. answered 8 mins ago

	If you started from the IDE, hit back, and then tapped the launcher icon, you will be starting another instance of your app. This might help explain things. answered 1 min ago

[android help] Trouble setting items in AlertDialog with OnClickListener

Change:

b.setItems(types, new OnClickListener){

To

b.setItems(types, new DialogInterface.OnClickListener){

And you will have to split

String[] types = {"1", "2", "3"};

to individual ints, or a CharSequence array.

You probably have an OnClickListener for another normal View in your code somewhere, and have it in your imports. As all OnClickListener classes share the same name, Eclipse auto resolves them all to the currently imported one. You can specify the parent class in such cases.

Additionally, the setItems() method that Eclipse has resolved takes a single int for the first parameter, not a String array. You could use the other setItems() method though, which takes a CharSequence Array. In such a case, change

String[] types = {"1", "2", "3"};

to

CharSequence[] types = {"1", "2", "3"};

[android help] Phonegap Android app trigger update programmatically

I am building an Android app that is hosted on a server outside Google Play. I need the app to check for new version and prompt user to update when the app starts.

I built a mechanism to check for new version (the app checks for a file on server and compares version) which is working well. Then I prompt user to update, but if user chooses to proceed with the update, I'm not able to trigger the download and installation of the apk.

I tried simply opening the apk url:

window.open(apkURL);

where the apkURL is the full http link to the .apk file hosted on server.

But it doesn't seem to do anything.

I've been researching but I don't find an answer on how to do this. I found some suggestions using native code, like this post Install Application programmatically on Android but I don't know how to do that from within my Phonegap app. Is this the right way to trigger the update? How can something like this be done from within a Phonegap app?

Thanks!

[General] Unable to change permissions or delete a specific file WITH root

Hello Gentlemen. Sorry to disturb you with a noob question but I cannot solve it for the life of me and I have tried everything I could find on the forums. I have an Aluratek Cinepad AT107F. I have successfully rooted it. I have full super user permissions and I have no problems deleting any files or folders EXCEPT one directory. Let me explain the situation.

I recently did a firmware update and it included brand new APKs for Youtube, also added Google Play Support, and added Angry Birds.

I am unable to update Youtube to the latest version. It gives a "Package file was not signed correctly. Uninstall the previous copy of the app and try again.".

So I attempted to do just what it had asked. I rooted just to do this. I tried removing it with Titanium Backup, I tried Root Uninstaller, I tried Root Explorer, I tried deleting using the "adb shell rm" command. I still get a "Read-only file system".

Even though I have root and granted root access to Root Explorer, I am unable to change the permissions for this /oem/apps/ directory. It's on the top level of the internal memory. I have no external SD card.

I've spent 10+ hours trying to figure this out and I'm sure someone knows something that I don't and can fix this super easy. I'm asking for your help, you're my only hope!
