You can create app locker with different logic, I will help you to understand what is required for implementing, I will explain my way so you can use it as example. To create app locker in android studio you need knowledge in these things are
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.util.Log;
public class RestartService extends BroadcastReceiver {
@Override public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Log.i("Broadcast Listened", "Service tried to stop");
//Toast.makeText(context, "Service restarted", Toast.LENGTH_SHORT).show();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(new Intent(context, BackgroundServices.class));
}
else {
context.startService(new Intent(context, BackgroundServices.class));
}
// context.startService(new Intent(context.getApplicationContext(), NotificationService.class));
}
Log.i("Broadcast Listened", "Service tried to stop");
//Toast.makeText(context, "Service restarted", Toast.LENGTH_SHORT).show();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(new Intent(context, BackgroundServices.class));
}
else {
context.startService(new Intent(context, BackgroundServices.class));
}
}
}
Very important code and that is how to track which app is currently running using stats services, code will return package name of app, below is the code
private void printForegroundTask() {
String currentApp = "NULL";
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
UsageStatsManager usm = (UsageStatsManager) this.getSystemService(Context.USAGE_STATS_SERVICE);
long time = System.currentTimeMillis();
List<UsageStats> appList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000*1000, time);
if (appList != null && appList.size() > 0) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
for (UsageStats usageStats : appList) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
}
} else {
ActivityManager am = (ActivityManager)this.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> tasks = am.getRunningAppProcesses();
currentApp = tasks.get(0).processName;
}
Log.e(TAG, "Current App in foreground is: " + currentApp);
}
In the latest API, google add restriction on background services and I was using background services in it, So for latest api you will use job scheduler instead of background service. That is simple solution.
Now let’s talk about buying code, so you will get code easily but that will be supported on Oreo API for now, New Source code which supported on latest api will be available after 1000 subscriber on youtube channel. You want to check demo below is link and paypal id for support or purchase code.
