ActivityNotFoundException, image capturing?

问题:

I have released an App which user can take photo in it.I do this to capturing photo:

File file = new File( _path );
Uri outputFileUri = Uri.fromFile( file );   
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra( MediaStore.EXTRA_OUTPUT, outputFileUri );      
startActivityForResult( intent, 0 );

and also I added this permission to manifest:

<uses-permission android:name="android.permission.CAMERA" />

I tested my App on Android2.3.5 and Android3.0,and it works fine.But when I run my App on Android4.0.3,it crashes:

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.media.action.IMAGE_CAPTURE (has extras) }

How I can solve this problem?

Check if your

1.Tablet has camera (if your using tablet). 2. A phone has camera 3. No SD card installed.

Add the below to manifest.

   <uses-feature android:name="android.hardware.camera" />

Will prevent apps being downloaded from google play. http://developer.android.com/google/play/filters.html

To check if your device has camera.

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.main);

    Context context = this;
    PackageManager packageManager = context.getPackageManager();

    // if device support camera?
    if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
        //yes
        Log.i("camera", "This device has camera!");
    }else{
        //no
        Log.i("camera", "This device has no camera!");
    }


}
}
