Failure delivering result ResultInfo{who=null, request=2, result=0, data=null} camera

提问by Guru Charan

here is the camera code

这是相机代码

   private void selectImage(){

 final  int Camera_CPTURE = 1;

try {
    Intent capture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(capture,Camera_CPTURE);
}catch (ActivityNotFoundException e)
{
    String error ="opps ur devices doesn't support capturing";
    Toast toast = Toast.makeText(this,error,Toast.LENGTH_SHORT);
    toast.show();
}
}




protected void onActivityResult(int requestCode, int resultCode, Intent data) {


    if (resultCode == RESULT_OK) {
        picUri = data.getData();
        performCrop();  }
    else if(requestCode == PIC_CROP)
    {
        Bundle extra = data.getExtras();
        Bitmap thePic = extra.getParcelable("data");
        ImageView picView = (ImageView)findViewById(R.id.imageView);
        picView.setImageBitmap(thePic);
    }

    }

private void performCrop() {
    try {
       Intent cropIntent = new Intent("com.android.camera.action.CROP");
        cropIntent.setDataAndType(picUri,"image/*");
        cropIntent.putExtra("crop","true");
        cropIntent.putExtra("aspectX",1);
        cropIntent.putExtra("aspectY",1);
        cropIntent.putExtra("outputX",200);
        cropIntent.putExtra("outputY",200);
        cropIntent.putExtra("return-data",true);
        startActivityForResult(cropIntent,PIC_CROP);

    }catch (ActivityNotFoundException e)
    {
        String error ="opps ur devices doesn't support capturing";
        Toast toast = Toast.makeText(this,error,Toast.LENGTH_SHORT);
        toast.show();
    }
}





@Override
public void onClick(View view) {
    if(view.getId()==R.id.button){
        selectImage();

    }

}
}

and the log is here

If u get error on Kotlin just mark the dataintent as @nullableby adding a ? after the Intent type declaration. So it should look like so:

如果妳得到科特林错误只是标记数据意图作为@nullable通过增加？在 Intent 类型声明之后。所以它应该是这样的：

data: Intent?.
