File object can't find the file when there is one [android help]

File object can't find the file when there is one

In my app After user clicks on a button ,the download manager starts to download a file from internet and saving it to the internal sd card using this code:

void startDownload()
    {
        Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).mkdirs();        
        download_req.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
        .setAllowedOverRoaming(false)
        .setTitle(PersianReshape.reshape("Downloading"))
        .setDescription(PersianReshape.reshape("currently downloading the file..."))
        .setDestinationInExternalPublicDir(Environment.getExternalStorageDirectory().getAbsolutePath() , packageId + ".sqlite");
        download_ID = mgr.enqueue(download_req);
    }

After it is downloaded, I plan to check its existance everytime app runs with this code:

String DatabaseAddress =
Environment.getExternalStorageDirectory().getAbsolutePath() +
"/ee.sqlite";
File file = new File(DatabaseAddress);
Log.d("PATH File: ", DatabaseAddress);
if (file.exists()){
Toast.makeText(getApplicationContext(), "found", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(getApplicationContext(), "not found", Toast.LENGTH_SHORT).show();
}

Now when I run this code it returns "not found" message whereas the file is already there (I checked its existance using a file manager).

the device I test on is nexus 7 and path used in saving the download file is: /storage/emulated/0/ee.sqlite

ee.sqlite is the filename of downloaded file.

/storage/emulated/0/ is the default path returned by app

Permissions added to manifest for this code are:

Q: Why does file.exists() returns false when there is a file?

Disable checkbox if X are checked in android [android help]

Disable checkbox if X are checked in android

I have 15 CheckBox and I must to stuck user when he checks more than 5 CheckBox. Is it possible? I used the method OnCheckedChangeListener to know if an item was checked... but I don't know how to make a limit after 5 items selected. See what I've tried to do below:

I instante my integer:

int lengthBox = 15;
int lenghtMax = 5;  

I select all my View in onCreate():

View[] tagsItem = new View[] { 
    findViewById(R.id.TagsCheckAA),
    findViewById(R.id.TagsCheckBB),
    findViewById(R.id.TagsCheckCC),
    findViewById(R.id.TagsCheckDD),
    findViewById(R.id.TagsCheckEE),
    findViewById(R.id.TagsCheckFF),
    findViewById(R.id.TagsCheckGG),
    findViewById(R.id.TagsCheckHH),
    findViewById(R.id.TagsCheckII),
    findViewById(R.id.TagsCheckJJ),
    findViewById(R.id.TagsCheckKK),
    findViewById(R.id.TagsCheckLL),
    findViewById(R.id.TagsCheckMM),
    findViewById(R.id.TagsCheckNN),
    findViewById(R.id.TagsCheckOO)
};  

I create 15 CheckBox:

final CheckBox[] tagsCheck = new CheckBox[lengthBox];  

Create the method (and it's here where I don't know what to do exactly):

OnCheckedChangeListener checker = new OnCheckedChangeListener(){ 
    @Override
    public void onCheckedChanged(CompoundButton cb, boolean b) {
          if(tagsCheck[0].isChecked() || tagsCheck[1].isChecked() || 
             tagsCheck[2].isChecked() || tagsCheck[3].isChecked() || 
             tagsCheck[4].isChecked() || tagsCheck[5].isChecked() || 
             tagsCheck[6].isChecked() || tagsCheck[7].isChecked() || 
             tagsCheck[8].isChecked() || tagsCheck[9].isChecked() || 
             tagsCheck[10].isChecked() || tagsCheck[11].isChecked() || 
             tagsCheck[12].isChecked() || tagsCheck[13].isChecked() || 
             tagsCheck[14].isChecked()) {  
            if(lenghtCount < 5){
                    // How can I get the String of the CheckBox 
                    // which just checked?
                String tags = (String) tagsCheck[].getText();
                Toast.makeText(getApplicationContext(), 
                tags + " checked", Toast.LENGTH_SHORT).show();
            }else{
                Toast.makeText(getApplicationContext(), 
                "Limit reached!!!", Toast.LENGTH_SHORT).show();
            }
        }
    }
};  

After this, I set my View id to my CheckBox and call the method:

for(int i = 0; i < lengthBox; i++) {
    tagsCheck[i] = (CheckBox) tagsItem[i];
    tagsCheck[i].setOnCheckedChangeListener(checker);
}  

Can someone point me in the right way, please?

Thanks, any help will be appreciate.

---

UPDATE:

I found an inelegant way with an if(tagsCheck[0].isChecked() || ...). But I have still a problem: how can I get the CheckBox which just checked? Cause of my if(), I don't know how can I do this.

Thanks!

MediaRecorder crash [android help]

MediaRecorder crash

---

Very beginner in Android/Java, coming from C and Symbian, I started from the Hellworld example to try to display the sound level (the project is to record this level in a text file for hours). This code is written in the MainActivity file, as a method inside the MainActivity Class :

public void GetAFlevel(View view) throws IllegalStateException, IOException {
    float audiolevel = 0, maxal = 0;
    MediaRecorder mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    mRecorder.setOutputFile("/dev/null");
    mRecorder.prepare();
    mRecorder.start();
    for (int i = 0; i < 1000; i++) {
        audiolevel = mRecorder.getMaxAmplitude();
        if (audiolevel > maxal)
            maxal = audiolevel;
    }
    EditText editText1 = (EditText) findViewById(R.id.editText1);
    editText1.setText(String.valueOf(maxal));
    mRecorder.stop();
    mRecorder.release();
    mRecorder = null;
}

The result is a crash of the application on the target :

11-17 00:23:09.859: D/AndroidRuntime(22096): Shutting down VM

11-17 00:23:09.859: W/dalvikvm(22096): threadid=1: thread exiting with uncaught exception (group=0x40018578)

11-17 00:23:09.921: E/AndroidRuntime(22096): FATAL EXCEPTION: main

11-17 00:23:09.921: E/AndroidRuntime(22096): java.lang.IllegalStateException: Could not execute method of the activity

No crash if I remove the following MediaRecorder functions : setAudioSource, setOutputFormat, setAudioEncoder, setOutputFile, prepare, start and stop, but getMaxAmplitude returns 0, of course.

As soon as I add only setAudioSource (normaly the only necessary for getMaxAmplitude), crash !

Any idea ?

Thanks in advance.

Why can't I take screenshots in Android Emulator after installing Genymotion? [android help]

Why can't I take screenshots in Android Emulator after installing Genymotion?

Tell me more ×

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

I've installed Genyomtion android emulator. Then I realized I can't take screenshots in Eclipse DDMS view. After that, I tried to take a screenshot with standard android emulator that comes with the SDK. It didn't work. Eclipse shows me a black image instead of screenshot. It worked before I installed Genymotion! It's suspicious that Genymotion hacked my ADB, because screenshot taking is part of PAID version of GenyMotion! Has anyone experienced the same problem? How can I get Eclipse taking screenshots again without reinstalling it? Thanks in advance! asked 18 hours ago Áron Nemmondommegavezetéknevem 286

	It's a known bug on 4.3 images, they are working on a fix. On a 4.2.2 image it's working for me, you can try to create a 4.2.2 device to take screenshot in the meantime. Source: On twitter @genymotion responded to @Littledot1230 on this question :) answered 12 hours ago

	I have just used Genymotion and Eclipse DDMS today to take a screenshot for an app store submission. So it works on at least these versions on my Win8 Pro machine: Genymotion v1.1.0 Android 4.2.2 10" image Eclipse ADT v22.0.1 Edit: so 4.2.2 is why mine worked - thanks Bonrry answered 18 hours ago Richard Le Mesurier 4,81912572

Android KitKat set language for Bluetooth voice dial [General]

Android KitKat set language for Bluetooth voice dial

Android KitKat set language for Bluetooth voice dial

Hi, i'm having a problem with my new Nexus 5. Please note this is my first android device.

I cant figure out how to change the input language for dialing with a bluetooth headset which is pretty annoying since most of my contacts have french names. Everything else works fine with french voice commands on the phone except for the bluetooth voice dialer which always specifies English on the top right.

Can anyone tell me how to change this? I would prefer to keep the menus un english if possible, but I have even tried removing english and setting french everywhere and it didn't change the voice dialing option.

Thank you

Storage [General]

Storage

My phone is really struggling for storage so I deleted a bunch of videos and pictures worth about 150Mb. That did not make a difference at all for some reason. Anyways if I go to Settings --> Apps --> Here I see my download phone memory is almost full but my internal storage is almost empty with almost 2GB free. And is RAM has just gone to **** and is literally full. Can I remove everything for downloads if its now on my internal storage? And what can I do about the RAM? Thanks.

Text inflation in Chrome on Nexus 5 [General]

Text inflation in Chrome on Nexus 5

First post and a new Android convert here, so excuse me if I at any point come across as a bit daft. Anywho...

I picked up a Nexus 5 last week and noticed that Chrome inflates text in places it shouldn't. I seems to happen on sites like Reddit or other forum/comment driven sites, with lots of text in lots of frames and elements and such. The top of the pages are fine, but after a certain point down the page everything becomes inflated. Screen cap linked to so you can see what I mean.

I haven't had the chance to play around with my phone nearly enough to confirm, but it seems to be specific to Chrome... Firefox and Opera render pages perfectly. I've reformatted the phone, made sure the OS and all apps are up to date, closed out all other apps, etc etc, to no avail. I've tried searching for an answer online, both here and elsewhere, but I can't seem to find anything. I even called Google, but the rep was a bit clueless and kept insisting it must be some kind of connectivity issue.

Anyway, it's not a huge thing, but it's annoying me to no end that I can't figure it out. Help?

Adding a marker results in NullPointerException in Android [android help]

Adding a marker results in NullPointerException in Android

This is a part of my project. I am getting an arraylist of longitude and latitude from the previous class. Without the marker code, the app is working properly but when I add the marker code the app is terminating due to NullpointerException. Can anyone tell me why ?

package xyz;

import...

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public class Route extends Activity {
GoogleMap map;
PolylineOptions polylineOptions;
ArrayList longitude,latitude;


@SuppressWarnings("unchecked")
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.route);
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

    double s_latitude = latitude.get(0);
    double s_longitude=longitude.get(0);


    /* If I add this line the app is terminating.
      map.addMarker(new MarkerOptions()
     .position(new LatLng(s_latitude,s_longitude))
    .title("Start Point"));
    */

    longitude = (ArrayList) getIntent().getSerializableExtra("Longitude");
    latitude = (ArrayList) getIntent().getSerializableExtra("Latitude");

    CameraUpdate center=
            CameraUpdateFactory.newLatLng(new LatLng(latitude.get(0),
                    longitude.get(0)));
        CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);

        map.moveCamera(center);
        map.animateCamera(zoom);



        polylineOptions=new PolylineOptions();

   for(int i=0;i   {
       polylineOptions.add(new LatLng(latitude.get(i), longitude.get(i)));
   }

       polylineOptions.color(Color.BLUE);
       polylineOptions.width(10);

        polylineOptions.geodesic(false);


        map.addPolyline(polylineOptions);


}
}
