When i click the button i calls the Asysnctask.I done it but after taking 2 three pictures I got outofmemory error and my app force closed. I tried to recycle(),null values but no use. Can any one tell how to avoid this error .This is the log i have got.</p> <pre><code> onCreate() { setContentView(R.layout.detail_profile); String fname=new File(getFilesDir(), "MyFile.jpeg").getAbsolutePath(); if(imgView!=null) { imgView.destroyDrawingCache(); } imgView=(ImageView)findViewById(R.id.imageView1); imgView.setImageURI(Uri.fromFile(new File(fname))); } public void onClick(View v) { if(checkInternetConnection()==false) { new AlertDialog.Builder(detailProfile.this).setTitle("Warning!").setMessage("No Internet connection").setIcon(R.drawable.icon).setNeutralButton("Close", null).show();
