Is There on Install Event in Android

Is there on install event in android?

There is the ACTION_PACKAGE_ADDED Broadcast Intent, but the application being installed doesn't receive this.

So checking if a preference is set is probably the easiest solution.

SharedPreferences p = PreferenceManager.getDefaultSharedPreferences(this);
boolean firstRun = p.getBoolean(PREFERENCE_FIRST_RUN, true);
p.edit().putBoolean(PREFERENCE_FIRST_RUN, false).commit();

Event when application gets installed (Android)

No you can't, the user has to explicitly start your application.

You can always check for the first time your application is launched.

Receiving package install and uninstall events

I tried to register the BroadcastReceiver in either manifest file or java code. But both of these two methods failed to trigger the onReceive() method.
After googling this problem, I found a solution for both methods from another Thread in SO:
Android Notification App

In the manifest file (this approach no longer applies since API 26 (Android 8), it was causing performance issues on earlier Android versions):

<receiver android:name=".YourReceiver">
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_INSTALL" />
        <action android:name="android.intent.action.PACKAGE_ADDED" />
        <data android:scheme="package"/>
    </intent-filter>
</receiver>

In java code:

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL);
intentFilter.addDataScheme("package");
registerReceiver(br, intentFilter);

This should work for you.

Android application install/uninstall event

Maybe someone will be interested. I found the code that allows me to checked system reboot after installation/update:

public static boolean phone_rebooted(Context ctx) {
        ApplicationInfo appInfo = ctx.getApplicationInfo();
        String appFile = appInfo.sourceDir;
        long installed = new File(appFile).lastModified();

        long boot_time = System.currentTimeMillis() - SystemClock.elapsedRealtime();
        if(boot_time < installed) {
           return false;
        } else {
           return true;
        }
    }

Android - catch the Cancel event when installing an .apk programmatically

You can add another Receiver to listen for the installed package

<receiver android:name=".ApkInstalledReceiver" android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.PACKAGE_ADDED" />
        <data android:scheme="package" />
    </intent-filter>
</receiver>

so, if the user cancels the installation you won't receive it.
