我試圖打開screenshots
照片文件夾。android.content.ActivityNotFoundException:找不到處理意圖的活動{act = android.intent.action.GET_CONTENT
private void Try3()
{
File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pictures/Screenshots");
Log.d("File path ", dir.getPath());
String dirPath=dir.getAbsolutePath();
if(dir.exists() && dir.isDirectory()) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
intent.setType("image/*");
intent.setData(Uri.fromFile(dir));
Log.d("b4performSpecificCrop_startActivityForResult::", Integer.toString(3));
startActivityForResult(intent, 3);
Log.d("afterperformSpecificCrop_startActivityForResult::", Integer.toString(3));
}
我有此權限的清單:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
,並從logcat中得到這樣的:
