I have just gotten into Android app development and have been working on parts of my project in bits and pieces.
I first created my onboarding screens and then made my animated splash screen. However, when I run my application my splash screen does not show and instead loads the onboarding pages first. How can I fix this to make my app first transition through the splash screen before moving on the onboarding screens?
This is my SplashActivity Class code
public class SplashActivity extends AppCompatActivity {
private static int SPLASH_SCREEN = 5000;
// Variables
Animation topAnim;
ImageView image;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_splash);
// Animations
topAnim = AnimationUtils.loadAnimation(this,R.anim.top_animation);
// Hooks
image = findViewById(R.id.splashScreenLogo);
image.setAnimation(topAnim);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(SplashActivity.this, OnboardingActivity.class);
startActivity(intent);
finish();
}
}, SPLASH_SCREEN);
}
}
This is my OnboardingActivity Class code
public class OnboardingActivity extends AppCompatActivity {
private OnboardingAdapter onboardingAdapter;
private LinearLayout layoutOnboardingIndicators;
private MaterialButton buttonOnboardingAction;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_onboarding);
// Onboarding Screens
layoutOnboardingIndicators = findViewById(R.id.layoutOnboardingIndicators);
buttonOnboardingAction = findViewById(R.id.buttonOnboardingAction);
setupOnboardingItems();
final ViewPager2 onboardingViewPager = findViewById(R.id.onboardingViewPager);
onboardingViewPager.setAdapter(onboardingAdapter);
setupOnboardingIndicators();
setCurrentOnboardingIndicator(0);
onboardingViewPager.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {
#Override
public void onPageSelected(int position) {
super.onPageSelected(position);
setCurrentOnboardingIndicator(position);
}
});
buttonOnboardingAction.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onboardingViewPager.getCurrentItem() + 1 < onboardingAdapter.getItemCount()) {
onboardingViewPager.setCurrentItem(onboardingViewPager.getCurrentItem() + 1);
}
else {
startActivity(new Intent(getApplicationContext(), SignUpActivity.class));
finish();
}
}
});
}
}
Edit - My Manifest File
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mentalhealthapp">
<application
android:allowBackup="true"

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

</application>
</manifest>
What should I change in my Manifest File?
You need to set the Launch activity as SplashActivity in your AndroidManifest.xml file
<activity
android:name=".SplashActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I cant use the back button on android right after clicking admob banner for about 60 second. The back button is like disabled for 60 second. after 60 second has passed, the back button back to normally.
i've try to Edit on Android Manifest and App activity but still no changes. got stuck for 2 days and dont have idea anymore.
here my manifest

I'm currently working on a simple android app. The idea is, it changes the wallpaper automatically after 12 A.M or when the date is changed. It's working on android Oreo and lower versions, however, it doesn't work on android 9(Pie). However, if I change the date manually from the setting of the phone, it calls the broadcast. I have googled a lot, and some suggested to register the broadcast on your java codes instead of Manifest. Unfortunately, it didn't work.
I have tested this question in Stackoverflow.
First of all, changing the date is not part of implicit broadcasts, secondly, I assumed it is. then I changed the codes but it didn't work.
Now I'm gonna provide some codes of my broadcast:
DailyBroadcastReceiverService
public class DailyBroadcastReceiverService extends Service {
private BroadcastReceiver dailyZekrBr;
private Context context;
#Nullable
#Override
public IBinder onBind(Intent intent) {

#Override
public void onCreate() {
super.onCreate();
registerDailyZekrReceiver();
}
#Override
public void onDestroy() {
super.onDestroy();
unregisterReceiver(dailyZekrBr);
dailyZekrBr = null;
}
private void registerDailyZekrReceiver() {
context= this.getApplicationContext();
Log.d("Register", "onStart: Now gonna register the broadcast receiver on Daily Boadcast receiver");
dailyZekrBr = new DailyZekrBroadcastReceiver();
IntentFilter filter = new IntentFilter();
filter.addCategory(Intent.CATEGORY_DEFAULT);
filter.addAction("android.intent.action.ACTION_TIME_CHANGED");
filter.addAction("android.intent.action.TIME_SET");
filter.addAction("android.intent.action.DATE_CHANGED");
filter.addAction("android.intent.action.TIMEZONE_CHANGED");
this.registerReceiver(dailyZekrBr, filter);
}
}
DailyZekrBroadcastReceiver
public class DailyZekrBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("DailyZekrBroadcast", "onReceive:The broadcast is called ");
DailyZekrHandler.setTodayImage(context);
}
}
setTodayImage
public static void setTodayImage(Context context) {
int todayImage = DailyZekrHandler.nameOfTheWeek();
DisplayMetrics metrics = new DisplayMetrics();
WindowManager window = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
window.getDefaultDisplay().getMetrics(metrics);
Log.d("DailyZekrBroadCast", "trying to change imge: " + todayImage);
if(todayImage != DailyZekrHandler.getTodayImage(context)) {
DailyZekrHandler.storeTodayImage(context);
Bitmap tempbitMap = BitmapFactory.decodeResource(context.getResources(), todayImage);
Bitmap bitmap = Bitmap.createScaledBitmap(tempbitMap, metrics.widthPixels, metrics.heightPixels, true);
WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);
wallpaperManager.setWallpaperOffsetSteps(1, 1);
wallpaperManager.suggestDesiredDimensions(metrics.widthPixels, metrics.heightPixels);
try {

Log.d("DailyZekrBroadCast", "today_image: " + todayImage);

I am trying to make a simple app that will forward all messages with particular body to another number.
Broadcast receiver in my class is not being called. Any leads will be appreciated
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Settings.Applog("App started !!");
Intent intent = new Intent(this, SMSService.class);
startService(intent);
}

{
super.onCreate();
Settings.Applog("Service started !!");
//SMS event receiver
mSMSreceiver = new SMSreceiver();
mIntentFilter = new IntentFilter();
mIntentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
registerReceiver(mSMSreceiver, mIntentFilter);
}
#Override
public void onDestroy()
{
super.onDestroy();
// Unregister the SMS receiver
unregisterReceiver(mSMSreceiver);
}
private String ConvertNumber(String from){
return from;
}
public class SMSreceiver extends BroadcastReceiver

#Override
public void onReceive(Context context, Intent intent)
{
Bundle bundle = intent.getExtras();
String strMessage = "";
Settings.Applog("Got a message!!");
if ( bundle != null )
{
try{
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] msgs = new SmsMessage[pdus.length];
for(int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
String msg_from = msgs[i].getOriginatingAddress();
String msgBody = msgs[i].getMessageBody();
Settings.Applog("Message body ::"+msgBody);
}
}catch(Exception e){
//Log.d("Exception caught",e.getMessage());
}
}
}
}
}
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:allowBackup="true"

You have to register the Broadcast Receiver for receiving SMS in the manifest file.
Just the permission will not work.
Inside the application tag it would look something like:
<application android:icon="#drawable/icon" android:label="#string/app_name" android:debuggable="true" >
<receiver android:name=".SMSBroadcastReceiver">
<intent-filter>
<action android:name="android.provider.telephony.SMS_RECEIVED"></action>
</intent-filter>
</receiver>
</application>
Use this as an example for receiving the SMS message. It should be a good starting point.

From everything I've seen on Stack Exchange and elsewhere, I have everything set up correctly to start an IntentService when Android OS boots. Unfortunately it is not starting on boot, and I'm not getting any errors. Maybe the experts can help...
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.phx.batterylogger"
android:versionCode="1"
android:versionName="1.0"
android:installLocation="internalOnly">
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.BATTERY_STATS" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<service android:name=".BatteryLogger"/>
<receiver android:name=".StartupIntentReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
BroadcastReceiver for Startup:
package com.phx.batterylogger;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class StartupIntentReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent serviceIntent = new Intent(context, BatteryLogger.class);
context.startService(serviceIntent);
}
}
UPDATE: I tried just about all of the suggestions below, and I added logging such as Log.v("BatteryLogger", "Got to onReceive, about to start service"); to the onReceive handler of the StartupIntentReceiver, and nothing is ever logged. So it isn't even making it to the BroadcastReceiver.
I think I'm deploying the APK and testing correctly, just running Debug in Eclipse and the console says it successfully installs it to my Xoom tablet at \BatteryLogger\bin\BatteryLogger.apk. Then to test, I reboot the tablet and then look at the logs in DDMS and check the Running Services in the OS settings. Does this all sound correct, or am I missing something? Again, any help is much appreciated.
Well here is a complete example of an AutoStart Application
AndroidManifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pack.saltriver" android:versionCode="1" android:versionName="1.0">

<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<activity android:name=".hello"></activity>
<service android:enabled="true" android:name=".service" />
</application>
</manifest>
autostart.java
public class autostart extends BroadcastReceiver
{
public void onReceive(Context context, Intent arg1)
{
Intent intent = new Intent(context,service.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.startForegroundService(intent);
} else {
context.startService(intent);
}
Log.i("Autostart", "started");
}
}
service.java
public class service extends Service
{
private static final String TAG = "MyService";
#Override
public IBinder onBind(Intent intent) {
return null;
}
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
}
#Override
public void onStart(Intent intent, int startid)
{
Intent intents = new Intent(getBaseContext(),hello.class);
intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intents);
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
}
}
hello.java - This will pop-up everytime you start the device after executing the Applicaton once.
public class hello extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Toast.makeText(getBaseContext(), "Hello........", Toast.LENGTH_LONG).show();
}
}
Following should work. I have verified. May be your problem is somewhere else.
Receiver:
public class MyReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(arg1.getAction())) {
Log.d("TAG", "MyReceiver");
Intent serviceIntent = new Intent(context, Test1Service.class);
context.startService(serviceIntent);
}
}
}
Service:
public class Test1Service extends Service {
/** Called when the activity is first created. */
#Override
public void onCreate() {
super.onCreate();
Log.d("TAG", "Service created.");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d("TAG", "Service started.");
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
Log.d("TAG", "Service started.");
}
#Override
public IBinder onBind(Intent arg0) {
return null;
}
}
Manifest:
<?xml version="1.0" encoding="utf-8"?>

Your Service may be getting shut down before it completes due to the device going to sleep after booting. You need to obtain a wake lock first. Luckily, the Support library gives us a class to do this:
public class SimpleWakefulReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// This is the Intent to deliver to our service.
Intent service = new Intent(context, SimpleWakefulService.class);
// Start the service, keeping the device awake while it is launching.
Log.i("SimpleWakefulReceiver", "Starting service # " + SystemClock.elapsedRealtime());
startWakefulService(context, service);
}
}
then, in your Service, make sure to release the wake lock:
#Override
protected void onHandleIntent(Intent intent) {
// At this point SimpleWakefulReceiver is still holding a wake lock
// for us. We can do whatever we need to here and then tell it that
// it can release the wakelock.
...
Log.i("SimpleWakefulReceiver", "Completed service # " + SystemClock.elapsedRealtime());
SimpleWakefulReceiver.completeWakefulIntent(intent);
}
Don't forget to add the WAKE_LOCK permission:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
I have found a way to make your application run well when the device reboots, please follow the steps below to be successful.
AndroidManifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="pack.saltriver" android:versionCode="1" android:versionName="1.0">
<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".UIBootReceiver" android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<service android:name=".class_Service" />
</application>
</manifest>
UIBootReceiver
public class UIBootReceiver extends BroadcastReceiver {
private static final String TAG = "UIBootReceiver";
#Override
public void onReceive(Context context, Intent arg1)
{
Toast.makeText(context, "started", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(context,class_Service.class);
context.startService(intent);
}
}
This is asking permission to not need to manage battery saving for this app so you can run in the background stably.
Declare this code in onCreate () of MainActivity class:
Intent myIntent = new Intent();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
myIntent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
myIntent.setData(Uri.parse("package:" +
DeviceMovingSpeed.this.getPackageName()));
}
startActivity(myIntent);
Looks very similar to mine but I use the full package name for the receiver:
<receiver android:name=".StartupIntentReceiver">
I have:
<receiver android:name="com.your.package.AutoStart">
I've had success without the full package, do you know where the call chain is getting interrupted? If you debug with Log()'s, at what point does it no longer work?
I think it may be in your IntentService, this all looks fine.
Just to make searching easier, as mentioned in comments, this is not possible since 3.1
