A simple, lightweight update checker for Android apps. It reads a JSON file you host yourself, compares the version code with the installed one, and hands you the result — you decide what dialog or snackbar to show.
- You host the JSON — GitHub raw, S3, your own server, anything reachable over HTTP
- Forceable updates — a
cancellableflag in the JSON lets you block the app until the user updates - No UI imposed on you — the library gives you the data, you build the dialog
- Tiny — one class, no dependency on Play Services or any update SDK
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}Add the dependency
dependencies {
implementation 'com.github.p32929:AndroidAppUpdater:1.0.2'
}Steps to follow:
- Create new
new AppUpdater(context, jsonUrl, listener) - Execute the task
- Do something if update is available
In your Activity or Fragment, you can add the code below:
new AppUpdater(this, "https://raw.githubusercontent.com/p32929/SomeHowTosAndTexts/master/Updater/updater.json", new UpdateListener() {
@Override
public void onJsonDataReceived(final UpdateModel updateModel, JSONObject jsonObject) {
if (AppUpdater.getCurrentVersionCode(MainActivity.this) < updateModel.getVersionCode()) {
new AlertDialog.Builder(MainActivity.this)
.setTitle("Update available")
.setCancelable(updateModel.isCancellable())
.setPositiveButton("Update", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(updateModel.getUrl()));
startActivity(browserIntent);
finish();
}
})
.show();
}
}
@Override
public void onError(String error) {
// Do something
}
}).execute();the JSON data should be like below:
{
"versionCode": 1, // Updated version code
"cancellable": false, // If you want to force users to update the app
"url": "http://tiny.cc/BuySellBD" // If you want users to update the app from an External URL or from the Google Play URL
}
If you add more data in the JSON file, you can get them from the jsonObject variable.
Hope you will enjoy using the library :) Thanks :)
