How pass params to my app when installed from local files or from Google Play?

How to Pass Parameters to Your Android App

Passing parameters to your Android app allows you to customize its behavior based on different situations, whether it’s installed from local files or from Google Play.

Passing Parameters from Local Files

Using Intent Data

You can pass parameters using Intent data when launching your app from local files. This method is suitable for scenarios like opening specific content within your app.

Code Example:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file:///sdcard/myfile.txt"), "text/plain");
startActivity(intent);

In your app’s manifest file, declare the intent filter:

Retrieving the data in your app:

Intent intent = getIntent();
Uri dataUri = intent.getData();
String filePath = dataUri.getPath();

Using Custom Scheme

Define a custom scheme for your app in the manifest and launch it with specific parameters using the scheme.

Code Example:

Launch the app with parameters:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("myapp://param1=value1¶m2=value2"));
startActivity(intent);

Retrieving parameters in your app:

Intent intent = getIntent();
Uri dataUri = intent.getData();
String query = dataUri.getQuery();
// Parse query parameters (e.g., using URLDecoder)

Passing Parameters from Google Play

Using App Bundles

App bundles allow you to create dynamic delivery features, providing different configurations based on parameters.

Creating App Bundles:

Use Android Studio to build your app bundle, including variations for different parameters.

Code Example:

// Retrieve parameters from App Bundle
String language = context.getString(R.string.app_language);
// Use the language to load appropriate resources

Using Dynamic Feature Modules

Split your app into dynamic feature modules, which can be downloaded on demand based on specific parameters.

Code Example:

// Define feature module dependencies
dependencies {
    implementation("com.google.android.gms:play-services-appinvite:17.0.0")
}
