Hier ist die Lösung. Danke Jungs für die Unterstützung. Es ist jetzt perfekt.

public void picselect(View view) { 

    Toast.makeText(this, "Select a pic", Toast.LENGTH_SHORT).show(); 
    Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
    startActivityForResult(i, RESULT_LOAD_IMAGE); 
} 

@Override 
protected void onActivityResult(int reqC, int resC, Intent data) { 
    if (resC == RESULT_OK) { 
     if (reqC == RESULT_LOAD_IMAGE) { 
      picUri = data.getData(); 
      performCrop(); 
     } else if (reqC == PIC_CROP) { 
      Bundle extras = data.getExtras(); 
      Bitmap thePic = extras.getParcelable("data"); 
      ImageView picv = (ImageView) findViewById(R.id.imageView); 
      picv.setImageBitmap(thePic); 
      imageView = (ImageView) findViewById(R.id.contimg); 
      imageView.setImageBitmap(thePic); 

     } 
    } 
} 

private void performCrop() { 
    try { 
     Intent cropIntent = new Intent("com.android.camera.action.CROP"); 
     cropIntent.setDataAndType(picUri, "image/*"); 

     cropIntent.putExtra("crop", "true"); 
     // indicate aspect of desired crop 
     cropIntent.putExtra("aspectX", 1); 
     cropIntent.putExtra("aspectY", 1); 
     // indicate output X and Y 
     cropIntent.putExtra("outputX", 200); 
     cropIntent.putExtra("outputY", 200); 
     // retrieve data on return 
     cropIntent.putExtra("return-data", true); 
     // start the activity - we handle returning in onActivityResult 
     startActivityForResult(cropIntent, PIC_CROP); 
    } catch (ActivityNotFoundException anfe) { 
     Toast t = Toast.makeText(this, "ANFE", Toast.LENGTH_SHORT); 
     t.show(); 
    } 
}
