    <p>I am integrating facebook with android and I want when taking a phot , save it to sdcard and then upload it to facebook.</p> <p>Here is my code:</p> <pre><code>photo_up=(Button)findViewById(R.id.camera_foto_button); photo_up.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(PlaceScreen.this)) ); startActivityForResult(intent,CAMERA_REQUEST); } }); private File getTempFile(Context context){ //it will return /sdcard/image.tmp final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName() ); if(!path.exists()){ path.mkdir(); } return new File(path, "image.png"); } </code></pre> <p>and the OnActivity Result</p> <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch(requestCode){ case CAMERA_REQUEST:{ final File file = getTempFile(this); try { bmp = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.fromFile(file) ); // do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc) } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } ByteArrayOutputStream stream = new ByteArrayOutputStream(); bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); byteArray = stream.toByteArray(); // convert camera photo to byte array Bundle params = new Bundle(); params.putByteArray("picture", byteArray); params.putString("message", "Have fun"); Utility.mAsyncRunner.request("me/photos", params, "POST", new PhotoUploadListener(), null); break; } </code></pre> <p>So what happens is this: Camera opens, imagae captured and saved but I get a force close and it is not uploaded on fb.</p> <p>I checked it on my phone,too. Logcat is here:</p> <pre><code>05-31 02:50:19.437: E/AndroidRuntime(2470): FATAL EXCEPTION: main 05-31 02:50:19.437: E/AndroidRuntime(2470): java.lang.RuntimeException: Unable to resume activity {com.myname.package/com.myname.package.PlaceScreen}: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1888, result=-1, data=Intent { act=inline-data (has extras) }} to activity {com.myname.package/com.myname.package.PlaceScreen}: java.lang.NullPointerException 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2124) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:2139) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1672) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.handleRelaunchActivity(ActivityThread.java:2836) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.access$1600(ActivityThread.java:117) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:939) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.os.Handler.dispatchMessage(Handler.java:99) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.os.Looper.loop(Looper.java:130) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.main(ActivityThread.java:3687) 05-31 02:50:19.437: E/AndroidRuntime(2470): at java.lang.reflect.Method.invokeNative(Native Method) 05-31 02:50:19.437: E/AndroidRuntime(2470): at java.lang.reflect.Method.invoke(Method.java:507) 05-31 02:50:19.437: E/AndroidRuntime(2470): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:867) 05-31 02:50:19.437: E/AndroidRuntime(2470): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:625) 05-31 02:50:19.437: E/AndroidRuntime(2470): at dalvik.system.NativeStart.main(Native Method) 05-31 02:50:19.437: E/AndroidRuntime(2470): Caused by: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1888, result=-1, data=Intent { act=inline-data (has extras) }} to activity {com.myname.package/com.myname.package.PlaceScreen}: java.lang.NullPointerException 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.deliverResults(ActivityThread.java:2536) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.performResumeActivity(ActivityThread.java:2111) 05-31 02:50:19.437: E/AndroidRuntime(2470): ... 13 more 05-31 02:50:19.437: E/AndroidRuntime(2470): Caused by: java.lang.NullPointerException 05-31 02:50:19.437: E/AndroidRuntime(2470): at com.myname.package.PlaceScreen.onActivityResult(PlaceScreen.java:325) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.Activity.dispatchActivityResult(Activity.java:3908) 05-31 02:50:19.437: E/AndroidRuntime(2470): at android.app.ActivityThread.deliverResults(ActivityThread.java:2532) 05-31 02:50:19.437: E/AndroidRuntime(2470): ... 14 more </code></pre> <p>edit:</p> <p>Ok my bmp where is null.

    3. CODoes your try/catch block surrounding the `getBitmap()` method fire either the `FileNotFoundException` or the `IOException`? Can you verify that file is actually on the SD card at the requested location with DDMS (I know you can see it in the gallery, but that doesn't mean it was saved where you asked it to be saved).

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).
