Starting an activity intent from a broadcast receiver shows the wrong activity

I am making a library that can be used to incorporate breaking and entering detection into any application
There is an arduino set to the alarm of the house which sends an SMS to a specific phone upon trigger
Within my sdk I register an sms receiver which upon receiving an sms with a specific text, should show a full screen activity (on top of the lockscreen too) that will alert the user
I created an application to test this behaviour
the application's package is : com.example.demo
the library's package is : com.example.sdk
the sms receiver looks like this:
class SMSReceiver : BroadcastReceiver() {
companion object {
const val TAG = "SMSReceiver"
}
private val logger by lazy { Injections.logger }
override fun onReceive(context: Context?, intent: Intent?) {
logger.log(TAG) { "Got sms" }
val ctx = context ?: return
val bundle = intent?.extras ?: return
val format = bundle.getString("format") ?: return
val pdus = (bundle["pdus"] as? Array<*>) ?: return
for (idx in pdus.indices) {
val pdu = pdus[idx] as? ByteArray ?: continue
val msg = SmsMessage.createFromPdu(pdu, format)
if (msg.messageBody.startsWith("theft event", true)) {
logger.log(TAG) { "Got theft event" }
abortBroadcast()
showTheftActivity(ctx, msg.messageBody)
break
}
}
}
private fun showTheftActivity(context: Context, messageBody: String) {
val intent = Intent(context, TheftActivity::class.java)
intent.addFlags(Intent.FLAG_FROM_BACKGROUND)
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
// .addCategory(Intent.CATEGORY_LAUNCHER)
val location = messageBody.split(" ").getOrNull(2)
if (location != null) {
val coords = location.split(",")
if (coords.size == 2) {
val x = coords[0].toBigDecimalOrNull()
val y = coords[1].toBigDecimalOrNull()
if (x != null && y != null) {
intent.putExtra(TheftActivity.X, x.toString())
intent.putExtra(TheftActivity.Y, y.toString())
}
}
}
context.startActivity(intent)
}
}
the activity that should show on top of everything is this :
class TheftActivity : Activity() {
companion object {
const val X = "locationX"
const val Y = "locationY"
}
private val x: String? by lazy { intent.getStringExtra(X) }
private val y: String? by lazy { intent.getStringExtra(Y) }
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_theft)
val location = findViewById<Button>(R.id.locate)
if (x != null && y != null) {
location.setOnClickListener { Toast.makeText(applicationContext, "Going to $x , $y", Toast.LENGTH_SHORT).show() }
location.isEnabled = true
finish()
} else {
location.isEnabled = false
}
findViewById<Button>(R.id.cancel).setOnClickListener {
finish()
}
turnScreenOnAndKeyguardOff()
}
private fun turnScreenOnAndKeyguardOff() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
setShowWhenLocked(true)
setTurnScreenOn(true)
} else {
window.addFlags(
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
or WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON
)
}
with(getSystemService(Context.KEYGUARD_SERVICE) as KeyguardManager) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
requestDismissKeyguard(this#TheftActivity, null)
}
}
}
override fun onDestroy() {
super.onDestroy()
turnScreenOffAndKeyguardOn()
}
private fun turnScreenOffAndKeyguardOn() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
setShowWhenLocked(false)
setTurnScreenOn(false)
} else {
window.clearFlags(
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
or WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON
)
}
}
}
and the sdk's android manifest contains this:
<application>
<activity
android:name=".ui.TheftActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:excludeFromRecents="true"
android:label="#string/title_activity_theft"
android:showOnLockScreen="true"
android:theme="#style/Theme.Sdk.Fullscreen" />
<receiver
android:name=".receivers.SMSReceiver"
android:enabled="true"
android:exported="true"
android:permission="android.permission.BROADCAST_SMS">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
when testing this on an emulator I send the sms to trigger the theft event
if the activity for testing (the one in the com.example.demo package) is not closed then it is brought to the front , but if it is closed nothing happens (though I do see the log messages from the receiver)
how can I make my sms receiver open the TheftActivity instead of the main activity from the main package?
edit: if it helps, the theft activity seems to start and then get immediately destroyed

It looks like the system can't bring the activity to the foreground due to the restrictions implemented in Android Q
With Android Q, it is impossible to start an activity from the background automatically if your app does not include those exceptions listed in the link below.

SMS retriever api android not working in vivo v15 pro, redmi note 4

I have successfully implemented SMS retriever in my application using the guideline here . My Code is working fine and otp is auto populated in many devices but some of the devices like vivo v15 pro, redmi note 4 it is not working (BroadcastReceiver's onReceive() not get triggered) . i have attached my code here. check and let me know if you have any solution for this. Thanks
Manifest.xml
<receiver
android:name=".sms.SMSRetrieverBroadcastReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.google.android.gms.auth.api.phone.SMS_RETRIEVED" />
</intent-filter>
</receiver>
SMSRetrieverBroadcastReceiver.kt
class SMSRetrieverBroadcastReceiver : BroadcastReceiver() {
companion object{
private var otpReceiver: OtpReceiver? = null
fun initOTPListener(receiver: OtpReceiver) {
this.otpReceiver = receiver
}
}
override fun onReceive(context: Context, intent: Intent) {
if (SmsRetriever.SMS_RETRIEVED_ACTION == intent.action) {
val extras = intent.extras
val status = extras!!.get(SmsRetriever.EXTRA_STATUS) as Status
when (status.statusCode) {
CommonStatusCodes.SUCCESS -> {
// Get SMS message contents
var otp: String = extras.get(SmsRetriever.EXTRA_SMS_MESSAGE) as String
Timber.d("OTP_Message "+otp)
if(otpReceiver != null) {
otpReceiver!!.onOTPReceived(otp)
}
}
CommonStatusCodes.TIMEOUT -> {
// Waiting for SMS timed out (5 minutes)
// Handle the error ...
if(otpReceiver != null) {
otpReceiver!!.onOTPTimeOut()
}
}
}
}}
MainActivity.kt
fun startListeningForSMS() {
SMSRetrieverBroadcastReceiver.initOTPListener(this)
startSmsListener()
}
private fun startSmsListener() {
val client = SmsRetriever.getClient(mContext)
val task = client.startSmsRetriever()
task.addOnSuccessListener {
Timber.d("Success")
}
task.addOnFailureListener {
Timber.d("Failed")
}
}
override fun onOTPReceived(otp: String) {
setReceivedOtp(otp)
}
override fun onOTPTimeOut() {
setReceivedOtp(null)
}

Go to Messeges-click on (:) on top left ->Go to setting->Disable prevention from Otp verification.It worked fine in my case.

Can you check with this intent-filter action:
<action android:name="android.provider.Telephony.SMS_RECEIVED" />

Why StartActivity(intent) failed? logcat show W/ActivityThread: handleWindowVisibility: no activity for token android.os.BinderProxy#

I am unsure what you mean by why StartActivity(intent) failed but based on your Logcat, it prints what I would expect from the code.
First of all it doesn't fail. You see in the Log that the code inside the onCreate() is executed. So the activity is started.
D/CategoryDetailRecyclerViewActivity: Intent:Intent { }
D/CategoryDetailRecyclerViewActivity: categoryDesignID: null
Here you see one of the problems: Your categoryDesignID is null. That is because you are not reading it from the right place. To get the data from the intent you used to start an Activity, you should ask for the intent instead of creating a new one.
Change your onCreate code to this and is should at least log the right id value:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_category_detail_recycler_view)
// don't create an Intent instance, it is already available and contains what you have send via startActivity(intent)
// var intent = Intent()
Log.d(TAG, "Intent:$intent ");
var categoryDesignID = intent.getStringExtra("categoryDesignID")
Log.d(TAG, "categoryDesignID: $categoryDesignID");
}

This problem has solved.
I later changed var intent = Intent() into var intent = getIntent(), then CategoryDetailRecyclerViewActivity can get intent.

App goes back to first activity if paused and relaunched from launcher icon

Basically, whenever I launch a second activity and pause the application and relaunch app by tapping on its icon in launcher, app does not resumes on second activity but goes back to first activity. On top of that, if I pause the app(view in task manager), which app makes shows whole activity again like really fast(talking in milliseconds) and then continues to task manager.

</application>
Since you would have noticed launchMode set to "singleTask", there is a reason behind it. My app contains recycler view. Its data is updated from second activity. Without launchMode set to singleTask, recyclerview data is not updated so to update the data I had to relaunch whole app just to see any data change. It is a temporary workaround but I am hoping if someone would help me on this matter as well.
About reycler view not updating, I have asked about that question countless times but never got a solution. Yes, I have gone through probably hundreds of similar problems on stack over flow and none of them work. Please bear in mind that I am beginner in Android development hence I do not have knowledge on advanced things like MvvM, RxJava or live data architecture.
P.S Just so any one gives a solution that I recall my data loader function again somewhere in onStart or on Resume, I have tried that countless times and it does not works. My app is not using fragments or any other advanced stuff just basic activities. Any help is appreciated!

You are invoking finish() in saveNote() method, which is being called in onPause(), hence every time your app goes into background, current activity is being finished (closed) due to invokation of finish() in it.
Remove the calls to finish() in saveNote() method, and you will be resumed to your current activity instead of landing on launcher/Main Activity.

You can try use this in MainActivty:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
if (Intents.isActivityExpandedFromLauncherIcon(this)) {
finish()
} else {
setContentView(R.layout.activity_main)
}
}
upd:
public class Intents {
public static boolean isActivityExpandedFromLauncherIcon(#NonNull Activity activity) {
return !activity.isTaskRoot() && isActivityStartedFromLauncherIcon(activity.getIntent());
}
public static boolean isActivityStartedFromLauncherIcon(#Nullable Intent intent) {
return intent != null &&
intent.hasCategory(Intent.CATEGORY_LAUNCHER) &&
intent.getAction() != null &&
intent.getAction().equals(Intent.ACTION_MAIN);
}
}

Spotify Auth Library returning Type.EMPTY on login

I followed everything in the android authentication guide and the quick start guide. I did as the guide told me to generate a SHA1 and adding it to Spotify app dashboard, and I got the app_client and added it to my app as well. Both scenarios still return the same thing. I even tried implementing the Login thru Browser feature, yet it still returns type EMPTY.
Here's my Login class
class SignInActivity : AppCompatActivity(), ConnectionStateCallback, Player.NotificationCallback {
private var mPlayer : SpotifyPlayer? = null
private val CLIENT_ID = //replace this
private val REDIRECT_URI = //replace this
private val REQUEST_CODE = 1337
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_login)
btnSignin.setOnClickListener {
val builder = AuthenticationRequest.Builder(CLIENT_ID, AuthenticationResponse.Type.TOKEN, REDIRECT_URI)
builder.setScopes(arrayOf("user-read-private", "streaming"))
val request = builder.build()
AuthenticationClient.openLoginActivity(this, REQUEST_CODE, request)
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, intent)
// Check if result comes from the correct activity
if (requestCode == REQUEST_CODE) {
val response = AuthenticationClient.getResponse(resultCode, intent)
Log.i("LoginActivity", Gson().toJson(response))
when (response.type) {
// Response was successful and contains auth token
AuthenticationResponse.Type.TOKEN -> {
Log.i("LoginActivity", "is equals to TOKEN")
val playerConfig = Config(this, response.accessToken, CLIENT_ID)
Spotify.getPlayer(playerConfig, this, object : SpotifyPlayer.InitializationObserver {
override fun onInitialized(spotifyPlayer: SpotifyPlayer) {
mPlayer = spotifyPlayer
mPlayer!!.addConnectionStateCallback(this#SignInActivity)
mPlayer!!.addNotificationCallback(this#SignInActivity)
}
override fun onError(throwable: Throwable) {
Log.e("LoginActivity", "Could not initialize player: " + throwable.message)
}
})
}
// Auth flow returned an error
AuthenticationResponse.Type.ERROR -> {
Log.i("LoginActivity", "ERROR!: $response.error")
}
AuthenticationResponse.Type.EMPTY -> {
Log.i("LoginActivity", "EMPTY!")
}
}
}
}
override fun onLoggedIn() {
Log.d("LoginActivity", "User logged in")
// This is the line that plays a song.
mPlayer!!.playUri(null, "spotify:track:2TpxZ7JUBn3uw46aR7qd6V", 0, 0)
}
}
and here's my AndroidManifest file
`
<uses-permission android:name="android.permission.INTERNET"/>

I'm trying to get a Type.TOKEN from this

Had this exact same issue myself, the problem is with this line in onActivityResult():
val response = AuthenticationClient.getResponse(resultCode, intent)
data should be passed as the second argument instead of intent.
The reason this isn't a compiler error is due to Kotlin turning getters and setters into properties, intent is a call to the Activity method getIntent().
