Android java binder FAILED BINDER TRANSACTION?

Question

I am trying to download an image from service and display it in activity but I keep getting

 java binder FAILED BINDER TRANSACTION

This is my service Code

public class DownloadImageService extends Service {

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    new LoadImageAsync().execute(intent.getStringExtra("type"));
    return Service.START_NOT_STICKY;
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

private class LoadImageAsync extends AsyncTask<String, Void, String> {
    byte[] compressedImage;
    Bitmap bmp;
    String img;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(String... params) {

        try {
            URL url = new URL(imgUrl);
            bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
            compressedImage = CompressBitmap.compresssImage(bmp);
            img = Base64.encodeToString(compressedImage, Base64.DEFAULT);

        } catch (IOException e) {
            compressedImage = null;
            bmp = null;
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        if (compressedImage != null) {
            Intent i = new Intent(getApplicationContext(), OtherCampaignActivity.class);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            i.putExtra("image_byte", img);
            startActivity(i);
        }
        stopService(new Intent(getApplicationContext(), DownloadImageService.class));
    }
}

}

Compress function

public static byte[] compresssImage(Bitmap b) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    b.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] compressedByteArray = stream.toByteArray();
    return compressedByteArray;
}

My ACTIVITY

public class OtherActivity extends AppCompatActivity {
private ImageView iv;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_other);
    iv = (ImageView) findViewById(R.id.imageViewCam);
    byte[] byteArray =      Base64.decode(getIntent().getStringExtra("image_byte"), Base64.DEFAULT);
    //        byte[] byteArray = getIntent().getExtras().getByteArray("image_byte");
    Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
    iv.setImageBitmap(bitmap);

}

@Override
public void onBackPressed() {
    super.onBackPressed();
    finish();
}
}

What is the issue in the code. The activity is not starting.

the app is not crashing. I only get this in logcat:

06-30 12:38:36.800 29992-29992/com.vt.enit E/JavaBinder﹕ !!! FAILED BINDER TRANSACTION !!!

It is probably due to large bitmap I guess.

Answer 1

It fails because you are trying to send an image as an intent extra and it is too large for it. You can't send image using IPC communication technics like intents or service/binder, there is a limit of 1mb/10mb depending on version of android.

Answer 2

Creating the cache of the image solves my problem

private LruCache<String, Bitmap> mMemoryCache;

@Override
protected void onCreate(Bundle savedInstanceState) {
...
// Get max available VM memory, exceeding this amount will throw an
// OutOfMemory exception. Stored in kilobytes as LruCache takes an
// int in its constructor.
final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);

// Use 1/8th of the available memory for this memory cache.
final int cacheSize = maxMemory / 8;

mMemoryCache = new LruCache<String, Bitmap>(cacheSize) {
    @Override
    protected int sizeOf(String key, Bitmap bitmap) {
        // The cache size will be measured in kilobytes rather than
        // number of items.
        return bitmap.getByteCount() / 1024;
    }
};
...
}

public void addBitmapToMemoryCache(String key, Bitmap bitmap) {
if (getBitmapFromMemCache(key) == null) {
    mMemoryCache.put(key, bitmap);
}
 }

public Bitmap getBitmapFromMemCache(String key) {
return mMemoryCache.get(key);
}
