I'm implementing functionality to take an image from the camera app and store it in app storage. This activity "NewWordActivity" handles the collection of entries for addition to a room database.
The app crashes when trying to create the URI to pass to the camera intent (highlighted below in the "TakePictureIntent" method). Am I implementing the intent incorrectly? Thanks!
public class NewWordActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
public static final String WORD_REPLY = "com.example.android.wordlistsql.WORD";
public static final String CAT_REPLY = "com.example.android.wordlistsql.CAT";
public static final String PIC_REPLY = "com.example.android.wordlistsql.PIC";
static final int REQUEST_IMAGE_CAPTURE = 2;
//DIR for Pictures
//final String picsDIR = getDir("Pictures", 0).toString();
private EditText mEditWordView;
String wordCategory;
String wordPhotoDIR;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_word);
mEditWordView = findViewById(R.id.edit_word);
//Category Spinner
Spinner categories = findViewById(R.id.category_spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.word_categories, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
categories.setAdapter(adapter);
categories.setOnItemSelectedListener(this);
//Choose Image Button
final Button choosePicButton = findViewById(R.id.button_getPic);
choosePicButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
TakePictureIntent();
//finish();
}
});
//Save Button
final Button saveButton = findViewById(R.id.button_save);
saveButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent replyIntent = new Intent();
if (TextUtils.isEmpty(mEditWordView.getText())) {
setResult(RESULT_CANCELED, replyIntent);
} else {
String word = mEditWordView.getText().toString();
replyIntent.putExtra(WORD_REPLY, word);
replyIntent.putExtra(CAT_REPLY, wordCategory);
setResult(RESULT_OK, replyIntent);
}
finish();
}
});
}
//Methods for Category Spinner
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
wordCategory = parent.getItemAtPosition(position).toString();
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
This is the method where the crash occurs.
//Methods for Picture Selector
private void TakePictureIntent(){
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //MediaStore.ACTION_IMAGE_CAPTURE
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
Toast.makeText(
getApplicationContext(),
R.string.error_photo_file,
Toast.LENGTH_LONG).show();
}
// Continue only if the File was successfully created
if (photoFile != null) {
/*App Crashes Here*/
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
/*.................*/
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
This is the onActivityResult Method for the camera intent. The app never makes it to the camera intent to make it here.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//Preview Image
ImageView picPreview = findViewById(R.id.picPreview);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
picPreview.setImageBitmap(imageBitmap);
}
}
This handles the creation of the file object for the URI to reference.
private File createImageFile() throws IOException{
//Create Name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "word_" + timeStamp;
File storageDIR = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, //Prefix
".jpg", //Suffix
storageDIR //Directory
);
//Save file and path
wordPhotoDIR = image.getAbsolutePath();
return image;
}
