    <p>I want to upload images on a Parse server using an AsnycTask. When I upload images without using AsyncTask I successfully upload and can retrieve images. I want to use AsyncTask because in my app two activities are using network permissions or if someone has another solution to do this please tell. Code of the Activity:</p> <pre><code>package com.example.faceb; import java.io.ByteArrayOutputStream; import java.io.File; import com.parse.GetDataCallback; import com.parse.ParseException; import com.parse.ParseFile; import com.parse.ParseObject; import android.app.Activity; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.os.AsyncTask; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.TextView; import android.widget.Toast; public class ListActivity extends Activity { ImageView image; TextView value; public Bitmap bm; public byte[] bitmapdata; public ByteArrayOutputStream data; String s = "FileName"; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_list); uploadTask task = new uploadTask(); task.execute(s); } private class uploadTask extends AsyncTask&lt;String, Void, String&gt;{ @Override protected void onPostExecute(String result) { image.setImageBitmap(bm); } @Override protected String doInBackground(String... params) { upload(); return null; } } public void upload (){ bm = BitmapFactory.decodeResource(getResources(), R.drawable.back); data = new ByteArrayOutputStream(); bm.compress(Bitmap.CompressFormat.JPEG, 40, data); bitmapdata = data.toByteArray(); ParseFile file = new ParseFile("hai.png", bitmapdata); file.saveInBackground(); ParseObject testObject = new ParseObject("TestObject"); testObject.put("puu", file); testObject.saveInBackground(); } } </code></pre> <p>Following is my error logcat</p> <blockquote> <p>10-12 01:10:46.944: E/ActivityThread(2233): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider 10-12 01:11:07.604: E/AndroidRuntime(2233): FATAL EXCEPTION: main 10-12 01:11:07.604: E/AndroidRuntime(2233): java.lang.NullPointerException 10-12 01:11:07.604: E/AndroidRuntime(2233): at com.example.faceb.ListActivity$uploadTask.onPostExecute(ListActivity.java:44) 10-12 01:11:07.604: E/AndroidRuntime(2233): at com.example.faceb.ListActivity$uploadTask.onPostExecute(ListActivity.java:1) 10-12 01:11:07.604: E/AndroidRuntime(2233): at android.os.AsyncTask.finish(AsyncTask.java:417) 10-12 01:11:07.604: E/AndroidRuntime(2233): at android.os.AsyncTask.access$300(AsyncTask.java:127) 10-12 01:11:07.604: E/AndroidRuntime(2233): at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:429) 10-12 01:11:07.604: E/AndroidRuntime(2233): at android.os.Handler.dispatchMessage(Handler.java:99) 10-12 01:11:07.604: E/AndroidRuntime(2233): at android.os.Looper.loop(Looper.java:123) 10-12 01:11:07.604: E/AndroidRuntime(2233): at android.app.ActivityThread.main(ActivityThread.java:4627) 10-12 01:11:07.604: E/AndroidRuntime(2233): at java.lang.reflect.Method.invokeNative(Native Method) 10-12 01:11:07.604: E/AndroidRuntime(2233): at java.lang.reflect.Method.invoke(Method.java:521) 10-12 01:11:07.604: E/AndroidRuntime(2233): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 10-12 01:11:07.604: E/AndroidRuntime(2233): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 10-12 01:11:07.604: E/AndroidRuntime(2233): at dalvik.system.NativeStart.main(Native Method) 10-12 01:11:09.014: E/ActivityThread(2274): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider 10-12 01:48:14.084: E/ActivityThread(2313): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider 10-12 01:48:45.323: E/ActivityThread(2334): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider 10-12 03:19:06.184: E/ActivityThread(2371): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider 10-12 03:19:31.614: E/ActivityThread(2393): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider</p> </blockquote>

    2. COstack trace means logcat? And saveInBackground is method provided by parse server. its built in method not created by me. Also when i start this activity i returned to previous activity. Doing this without asynctask in a separate project everything works fine.

    3. COI don't know anything about facebook apis, but it looks like your problem comes from that. Specifically the inability to find whatever provider is needed for the apis to work. Try verifying your library links and refresh (clean) your project.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
