I'm new to Android. I wrote my activity in Kotlin and my tests in Java. I'm trying to run an espresso test on an android app and I have the following error message when trying to load a file from within my main activity. Can anyone help?
Here is the code I'm using for the function that loads the data from the file inside my Activity class:
fun loadImage(uri: Uri){
//get the input stream of the image selected using its uri
val inputStream = contentResolver.openInputStream(uri)
}
To run the test, I manually added a file to the emulator to get its uri. This next code is of the test:
@RunWith(AndroidJUnit4.class)
public class testGallery {
@Rule
public IntentsTestRule<MainActivity> mActivity = new IntentsTestRule<> (MainActivity.class);
@Rule
public GrantPermissionRule grantPermissionRule = GrantPermissionRule.grant(android.Manifest.permission.ACCESS_FINE_LOCATION);
@Test
public void test_uploadImage() {
Uri uri = Uri.parse("content://com.android.providers.downloads.documents/document/32");
Intent resultData = new Intent();
resultData.setAction(Intent.ACTION_OPEN_DOCUMENT);
resultData.putExtra("Uri", uri);
Instrumentation.ActivityResult result = new Instrumentation.ActivityResult(Activity.RESULT_OK, resultData);
this.mActivity.getActivity().grantUriPermission("com.intern_firstapp_juan", Uri.parse("content://com.android.providers.downloads.documents/document/32"), Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
mActivity.getActivity().uploadImage(uri);
}
}
Finally, this is the stack trace that appears when running the test.
java.lang.SecurityException: Permission Denial: opening provider com.android.providers.downloads.DownloadStorageProvider from ProcessRecord{54c088b 24178:com.example.hdhanushkodi.myapplication/u0a88} (pid=24178, uid=10088) requires that you obtain access using ACTION_OPEN_DOCUMENT or related APIs
