Question

当我想发送＆＃34;拍照意图＆＃34;时，问题就开始了。在htc one +（我测试我的应用程序的手机上），似乎这个意图对于我的应用程序来说太重了，它调用onTrimMemory方法（当你的应用消耗太多内存并且即将停止时显然会调用该方法）然后应用程序停止。所以我决定在处理Intent的AsyncTask上调用cancel（）方法。但接下来该怎么办？以下是相关摘录：

 private class djford extends AsyncTask<Void,Void,Void>{

    @Override
    protected Void doInBackground(Void... voids) {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                startActivityForResult(takePictureIntent, TAKE_PHOTO_CODE);
            while(1>0){
                if(isCancelled()){
                    ***// WHAT SHOULD I DO HERE??***
                }
            }

        }

        return null;
    }
}

@Override
public void onTrimMemory(int level) {
    if (level >= ComponentCallbacks2.TRIM_MEMORY_RUNNING_LOW) {
        fff.cancel(false);
        tv1.setText("canceled before stopping");
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode==RESULT_OK){
        if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) 
                Bundle extras = data.getExtras();
                Bitmap imageBitmap = (Bitmap) extras.get("data");
                ImageView.setImageBitmap(imageBitmap);

        }
        else {
            Uri returnUri = data.getData();
            imageView.setImageURI(returnUri);
        }
    }
    else
    {
        return;
    }
}
