Question

当我尝试在桌面上设置壁纸时，我收到此消息。为什么？以及如何删除此消息？

我的代码： - 点击按钮：

Intent intent = new Intent();                                                     
intent.setAction(Intent.ACTION_ATTACH_DATA);                                      
intent.addCategory(Intent.CATEGORY_DEFAULT);                                      
intent.setDataAndType(ContactsContract.Contacts.CONTENT_URI, "image/*");          
intent.putExtra("mimeType", "image/*");                                           
startActivityForResult(Intent.createChooser(intent, "Select service:"), position);

然后onActivityResult：

@Override                                                                      
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);                     

    resultView.setDrawingCacheEnabled(true);                                   
    Bitmap bitmap = resultView.getDrawingCache();                              
    new TaskSetWallpaper(GalleryActivity.this).execute(bitmap);                
}

和设置壁纸的内部类：

public class TaskSetWallpaper extends AsyncTask<Bitmap, Void, Bitmap>                              
{                                                                                                  
    private Context context;                                                                       
    private ProgressDialog pDialog;                                                                

    TaskSetWallpaper(Context context)                                                              
    {                                                                                              
        this.context = context;                                                                    
    }                                                                                              

    @Override

    {                                                                                              
        super.onPreExecute();

试试这可能对你有用。我通过以下解决方案解决了这个问题：

Intent intent = new Intent("com.android.camera.action.CROP");
//add below two line
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

无法编辑50x50像素以下的图像
