I want to show selected images from gallery with gridview.
But, all the tutorial is just get image from project file..
like this..
// Keep all Images in array
public Integer[] mThumbIds = {
R.drawable.pic_1, R.drawable.pic_2,
};
I coded like there is add button, if users click it,
user can save name and photo. And if they save it, shows the photo with gridview..
those data would save in sqlite db.
How can I show the image from sqlite?

I am using jitsi-android-sdk in which when I go click home screen it takes me to the picture in picture mode and when I click on the app takes me back to the first form page. How should full screen the picture in picture mode when I click on the app?
what should I put in onResume() so I can full-screen picture in picture on click of the app.
For example, When we are using Netflix and watching a movie on mobile when we press the home button it enters the picture in picture mode and when we click on the app icon it fullscreen the picture in picture mode (return to the movie in fullscreen which we are watching)
I want to implement the same behavior in my android app.
The first check which activity is going to paused state when the app goes picture in picture on that activity onResume() method add this code.
#Override
protected void onResume() {
super.onResume();
SharedPreferences sharedpreferences = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
//get boolean value from shared preferences which we are store when joining meeting button is clicked
boolean check = sharedpreferences.getBoolean(met,false);
if (check){
//if meeting is going on redirect to meeting
//Replace JitsiMeetAcitvity.class with your picture in picture activity class
startActivity(new Intent(this, JitsiMeetActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT));
}
}
I have used the shared preferences to keep the track of the meeting is going on or not.

Android system's default photo viewing app is used as the default viewer. It functions normally.
The code for photo viewing button is as follows:
//view source image
public void viewSourceClicked(View view){
Uri uri = getImageUri(this, MethodCommons.convertByteArrayToBitmap(itemToBeEdited.getOriginalImage()));
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
}
Except, when viewer's share button is pressed showing the share menu, if the user presses power button (closes the screen), then clicking this button after resuming the activity results only in a black screen.
Restarting the app containing the photo-viewing button does not resolve the issue.
This black screen can only be resolved by opening the default photo viewing app and click the share button once. So I figure that it relates to photo viewer's share activity being left open somehow.
How to prevent such black screen from occurring? any other suggestions?
Eventually I figured out that this resulted from using MediaStore.Images.Media.insertImage.
Using FileProvider in place of insertImage solved the problem.

I'm currently doing a Widget in Android. It is on the market and it's free.
I want to surprise the users by let them choose a picture they want to show in the widget.
Now...
If the widget is clicked, a PreferenceActivity appears. <-- Works!
In this Activity the user should be able to choose a picture from the phone picture gallery. <-- HOWTO?
After the User selected the prefered picture, the picture path or the drawable object should be stored in the SharedPreferences. <-- Would be really nice!
Is there any solution?
Thx!
In order to get an image from the Gallery, you must send an intent to start up the Gallery for the user to choose an image as such
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 10);
This will start the gallery and will call onActivityResult within your activity.
