Upload a photo from camera or gallery in android

Having the following error:
android.os.FileUriExposedException: file:///storage/emulated/0/temp.jpg exposed beyond app through ClipData.Item.getUri()
when I choose Option Camera from chosen AlertDialog
And the following error when I try to choose a photo from Gallery:
BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: /storage/emulated/0 (Is a directory)
The Gallery opens up, but I can't choose an image to set it to my ImageView

Class variable not changing in IF or Switch statements

Seems simple, but I can't get it to work. I have a public class string variable that should change within a if or switch statement. I haven't declared the variable inside the statement so it should change given the scope, no? But it only reads "FROM" and when I do go to change it in the if statement that applies, it does change to "TO" but only in that instance and reverts back to "FROM". I would pass it along the methods, but the full code is more cluttered and I don't think it's possible to do so.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
String typeOfText = "FROM";
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantRequest) {

The reason the code keeps reverting is because the call to readImage() is in onActivityResult() which recreates the activity when called. So basically, you are getting a fresh object, and the onTypeText() is reinitialized. onActivityResult() is basically a callback from your previous activity.

Your onClick() is not being called due you don't assign clicklistener to R.id.faboptions_favorite and the other View
in onCreate add :
findViewById(R.id.faboptions_favorite).setOnClickListener(this);
and same for the other view.

Camera Issue in Android

I am trying to open camera intent in my app.But I just need to make sure that the image doesn't get saved in either the SD Card or in the Internal Storage.Also the image should get displayed in the app when the picture is clicked.

This is what i have implemnted till now. But it doesn't give me the image back in the activity if it is stored in SD Card. Also the image is getting saved. Is is possible not to save the image in the storage media?
Thanks

A simple demo:

you need add permission

When it intent to Activity B, my app will exit automatically. But it will works if the image is captured image. Is it because the size too large? I have no ide on this.Can someone help me? Thanks a lot!

You shouldn't put bitmap into Bundle. The best way is saving image on storage and pass path uri between activities.

byte [] recieve = getIntent().getByteArrayExtra("key",defaultValue);

Replace the original image on a new image in android application

In this MainActivity java class on Android Application Project I can't replace the original image given by the system with the one different selected from the photo gallery of smartphone.
When I select the one different photo I have always the original image.
public class MainActivity extends Activity implements OnClickListener {
Button uploadButton, btnselectpic;
ImageView imageview;
private ProgressDialog dialog = null;
private String imagepath = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
uploadButton = (Button) findViewById(R.id.uploadButton);
btnselectpic = (Button) findViewById(R.id.btnselectpic);
imageview = (ImageView) findViewById(R.id.imageview);
btnselectpic.setOnClickListener(this);
uploadButton.setOnClickListener(this);
#Override
public void onClick(View arg0) {
if (arg0 == btnselectpic) {
selectImage();
} else if (arg0 == uploadButton) {
dialog = ProgressDialog.show(MainActivity.this, "",
"Uploading file...", true);
messageText.setText("uploading started.....");
new Thread(new Runnable() {
public void run() {
}
}).start();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && requestCode == 2 && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
imagepath = getPath(selectedImageUri);
Bitmap bitmap = BitmapFactory.decodeFile(imagepath);
imageview.setImageBitmap(bitmap);
messageText.setText("Uploading file path:" + imagepath);
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri, projection, null, null,
null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
private void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery",
"Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment
.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
} else if (options[item].equals("Choose from Gallery")) {
Intent intent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}

The problem is that your onActivityResult() will never do anything.
You start this method off with:
if (requestCode == 1 && requestCode == 2 && resultCode == RESULT_OK) {
// ...
}
requestCode cannot be both 1 and 2, so this conditional will always be false.
You are likely looking for something more like this:
if ((requestCode == 1 && resultCode == RESULT_OK) ||
(requestCode == 2 && resultCode == RESULT_OK)) {
// ...
}
