[General] How to get Google+ Instant Upload free storage for any photo

You know that Google+ Instant Upload photos don't count against your storage, but do you want that free storage for any photo at all? Here is a little workaround

Simple, but effective: just hook your phone up to your computer and drag and drop any photos you want into your phone's camera folder and, viola, they are treated like newly taken photos and uploaded to G+. (or use a file manager right on your phone to copy and paste there). Then, just delete those photos from the camera folder afterwards.

Now, keep in mind that they will be reduced to the "free upload" pixel limit of 2048, just like any other instant uploads, but for many of us, our camera phone pictures are not much bigger anyway.

Extra pro-tip: videos are also "free storage" and they don't reduce their quality at all. You can really maximize your free G+ storage with video.

[android help] Change TextView inside Fragment

Tell me more ×

Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required.

I followed this guy's tutorial on how to make an ActionBar. Let's say I want to change the TextView inside one of the fragments. So I added this on my StartActivity.java, under onCreate: TextView textview = (TextView) findViewById(R.id.textView1); textview.setText("HI!"); When I start my app, it crashes. Can somebody point me to the right direction? I hope somebody takes the time to look at the guy's tutorial because his layout is basically the same as mine. Thank you. asked 23 mins ago

If you want change your component, I suggest you to make a method inside the fragment like this: import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; public class DetailFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.details, container, false); return view; } public void setText(String text){ TextView textView = (TextView) getView().findViewById(R.id.detailsText); textView.setText(text); } } answered 12 mins ago

[android help] Creating the folder with password protection

I am trying to create the media recorder for Android by creating the folders with password protection and audio files inside.

But now I only can create the folder and audio files which other Apps and user of the Android smartphone to access.

The purpose of implementing password protection is to not to let other Apps or users can access the file and folders unless password is provided?

Are there any ideas how to achieve this besides creating the password entering panel?

The below is my code.

public void onClick(View view) throws Exception {
    if (count == 0) {

        tbxRecordStatus.setText("Record");
        btnRecord.setText("Stop Record");
        Toast.makeText(MainActivity.this, "Recording Starts",
                Toast.LENGTH_SHORT).show();
        String dateInString =  new SimpleDateFormat(
                "yyyy-MM-dd-HH-mm-ss").format(new Date()).toString();
        String fileName = "TasB_" + dateInString + " record.3gp";
        SDCardpath = Environment.getExternalStorageDirectory();
        myDataPath = new File(SDCardpath.getAbsolutePath()  + "/My Recordings");
        if (!myDataPath.exists())
            myDataPath.mkdir();

        audiofile = new File(myDataPath + "/" + fileName);
        recorder = new MediaRecorder();
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
        recorder.setAudioEncodingBitRate(16);
        recorder.setAudioSamplingRate(44100);
        recorder.setOutputFile(audiofile.getAbsolutePath());



        try
        {
         recorder.prepare();
        }
        catch (Exception e) 
        {
            e.printStackTrace();
        }
        recorder.start();

My problem is that when I am on a call and I receive another call, I get the notification beeping sound, and the person I am talking to also hears the beep and becomes aware that someone is trying to call me! The person I'm talking to should not hear the beep or know that I'm being called by a third person!

How can I resolve this issue? And how to prevent/turn off the beep to the person I am talking to without turning off call waiting ?

Please help.

Thanks.

[android help] Search through android app

Are you trying to implement search functionality in listView...

you can create EditText above ListView and implement TextChangeListener...

In here, as per the input string of EditText you can filter the listView.

inputSearch.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
        // When user changed the Text
        MainActivity.this.adapter.getFilter().filter(cs);  
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
            int arg3) {
        // TODO Auto-generated method stub

    }

    @Override
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub                         
    }
});

Try this link..

This will guide you in proper direction..

[android help] encryption and decryption using RSA in android app

i have been trying to develop an android app which could encrypt and decrypt the SMS of the inbox..but there is some error in the public key and private key.. here is my code

 public static PublicKey generateRsaPublicKey(BigInteger modulus, BigInteger publicExponent)

[android help] R file is missing android

I had this same issue today and figured it out. The reason this happens so often when including external/example files is because often times these examples reference layouts in your application, but do not have access to the package and therefore cannot see the R.java file in that package. to make things clear, here's the beginning of the R.java file:

/* AUTO-GENERATED FILE.  DO NOT MODIFY.
 *
 * This class was automatically generated by the
 * aapt tool from the resource data it found.  It
 * should not be modified by hand.
 */

package com.conceptualsystems.dashboard;

public final class R {
    public static final class attr {
    }
    public static final class drawable {
        public static final int csc_logo=0x7f020000;
        public static final int icon=0x7f020001;
    }
    public static final class id {
        public static final int activation_code=0x7f070012;
        public static final int alpha_bar=0x7f07000b;
        public static final int alpha_label=0x7f07000a;

notice the package name is whatever the package name of your application is. .java files that are not included in this package (ie, your example code you just dropped in) will need to explicitly reference that package file like this:

package com.example.android.apis.graphics;

import android.app.Dialog;
import android.content.Context;
import android.graphics.*;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.SeekBar;
import com.conceptualsystems.dashboard.R;

the last line is the one to pay attention to. after importing the resources explicitly, the resources will be available in your example code.

[android help] How do you implement a FileObserver from an Android Service

How do you structure an Android app to start a Service to use a FileObserver so that when the observed directory is modified (ie user takes picture) some other code executes. When debugging, the onEvent method is never triggered.

Here is the onStart event I have in my Service. The Toast fires for "My Service Started..."

public final String TAG = "DEBUG";
public static FileObserver observer;    

@Override
public void onStart(Intent intent, int startid) {       
        Log.d(TAG, "onStart");

        final String pathToWatch = android.os.Environment.getExternalStorageDirectory().toString() + "/DCIM/Camera/";       
        Toast.makeText(this, "My Service Started and trying to watch " + pathToWatch, Toast.LENGTH_LONG).show();

        observer = new FileObserver(pathToWatch) { // set up a file observer to watch this directory on sd card
            @Override
            public void onEvent(int event, String file) {
                //if(event == FileObserver.CREATE && !file.equals(".probe")){ // check if its a "create" and not equal to .probe because thats created every time camera is launched
                    Log.d(TAG, "File created [" + pathToWatch + file + "]");

                    Toast.makeText(getBaseContext(), file + " was saved!", Toast.LENGTH_LONG);                  
                //}
            }
        };
    }

But after that Toast, if I take a picture the onEvent never fires. This is determined by debugging. It never hits that breakpoint and the Toast never fires.

When that directory is browsed, the new image is saved there.

How do you get a FileObserver working in a Service?

[General] Hands free texting in Android

Hi!

I'm new to Android. Having grown tired of waiting on Sprint to put out a new Windows Phone, I succumbed to the siren song of the HTC One, which has made me pretty happy on the whole. It's a beautiful, powerful phone, and I can now have all of the apps I ever dreamed of-- certainly not the case for Windows Phone. So that's a big plus.

One thing, however, that I am missing a very great deal is the way that Windows Phone handles texting when you have headphones on. To wit: I receive an incoming message. The phone breaks in to my music to inform me of the message and asks me if I'd like it read to me. It then gives me the option of replying to the message, and, if I elect to do so, will take dictation from me and transcribe my reply, read it back to me, and either send it off or give me another stab at it, as I instruct. All of this is 100% hands-free, requiring absolutely no visual or tactile effort on my part. Nor does it require me to launch and keep running a battery-draining app.

I had come to utilize this functionality fairly heavily, so I've kinda been looking for a way to make Android behave this way, but I have failed. Before giving up completely, I thought I'd pose the problem to experienced Android fans and see if there is something that I may be overlooking.

So, is there?

My intent is not to start a religious war on phone platforms, I'm just interested in making my One work in the above manner with regards to texting.

Thank you in advance for any replies.
