super.onViewCreated(view, savedInstanceState)
this.ctx = view.context
//get the devie manifrature name
System.out.println(android.os.Build.MANUFACTURER)
//get the type of the bluetooth device
getBluetoothDeviceType()
checkPermission(

Change context of intent android

I have a service start with:
override fun onActivityResult(
requestCode: Int,
resultCode: Int,
data: Intent?
) {
if (requestCode == com.robertohuertas.endless.MainActivity.REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {
val intentx:Intent =ScreenCaptureService.getStartIntent(this,resultCode,data)
startService(intentx)
when phone reboot i will restart serive. i saved intent in sharedPreferences. But when phone after reboot context is different,now i get intent as code(intentx):
class StartReceiver : BroadcastReceiver() {
private val PREFS_KEY_intent = "myPreferncesintent"
private val PASSWORD_KEY_intent = "myPreferncesintent"
var intentx: Intent? =null
#RequiresApi(Build.VERSION_CODES.O)
override fun onReceive(context: Context, intent: Intent) {
val sharedPreferences: SharedPreferences =
context.getSharedPreferences(PREFS_KEY_intent, Context.MODE_PRIVATE)
val key= sharedPreferences.getString(PASSWORD_KEY_intent, "")
try {
intentx= Intent.parseUri(key, 0)
} catch (e: URISyntaxException) {
// TODO Auto-generated catch block
e.printStackTrace()
}
in short Example :Intent intent = new Intent(context, com.robertohuertas.endless.ScreenCaptureService.class); How to change context in this "intent"

Put intent to sharedPreferences return ""

Hello I have a mediaproject service. I start it with startActivityForResult
override fun onActivityResult(
requestCode: Int,
resultCode: Int,
data: Intent?
) {
if (requestCode == com.robertohuertas.endless.MainActivity.REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {
val bundle = data?.extras
if (bundle != null) {
for (key in bundle.keySet()) {
Log.d("TAGTAGTAGTAGTAGTA_st", key + " : " + if (bundle[key] != null) bundle[key] else "NULL")
}
}
// GlobalConstant.datax=data;
val sharedPreferences = getSharedPreferences(
PREFS_KEY_intent, MODE_PRIVATE
)
val editor = sharedPreferences.edit()
val uriString: String = data!!.toUri(requestCode)
editor.putString(PASSWORD_KEY_intent, uriString)
editor.commit()
Log.d("main_asssssssss","bolssss "+uriString)
startService(
com.robertohuertas.endless.ScreenCaptureService.getStartIntent(
this,
resultCode,
data
)
)
}
}
}
I want to save intent and use it after phone reboot but i can't get in onActivityResult
The result of Log.d("TAGTAGTAGTAGTAGTA_st" is android.media.projection.extra.EXTRA_MEDIA_PROJECTION : android.os.BinderProxy#6bb5fa5
,but result of Log.d("main_asssssssss","bolssss "+uriString) is D/main_asssssssss: bolssss don't have see uriString,it is "". where is my wrong?
NEW
I try as #muhammad-shuja this code:
override fun onActivityResult(
requestCode: Int,
resultCode: Int,
data: Intent?
) {
val intentx:Intent=ScreenCaptureService.getStartIntent(this,resultCode,data)
ScreenCaptureService.getStartIntent is:
public static Intent getStartIntent(Context context, int resultCode, Intent data) {
Intent intent = new Intent(context, com.robertohuertas.endless.ScreenCaptureService.class);
intent.putExtra("ACTION", START);
intent.putExtra("RESULT_CODE", resultCode);
intent.putExtra("DATA", data);
return intent;
}
I saved value intentx.getExtras()?.getString("DATA") to sharedPreferences
val editor = sharedPreferences.edit()
val xsd=intentx.getExtras()?.getString("DATA")
editor.putString(PASSWORD_KEY_intent, xsd)
editor.commit()
BroadcastReceiver
class StartReceiver : BroadcastReceiver() {
private val PREFS_KEY_intent = "myPreferncesintent"
private val PASSWORD_KEY_intent = "myPreferncesintent"
var telApp: Intent? =null
#RequiresApi(Build.VERSION_CODES.O)
override fun onReceive(context: Context, intent: Intent) {
// Toast.makeText(
// this#StartReceiver,
// "Tải mô hình không thành công onOrientationChanged！",
// Toast.LENGTH_SHORT
// ).show()
if (intent.action == Intent.ACTION_BOOT_COMPLETED && getServiceState(context) == ServiceState.STARTED) {
val sharedPreferences: SharedPreferences =
context.getSharedPreferences(PREFS_KEY_intent, Context.MODE_PRIVATE)
val password = sharedPreferences.getString(PASSWORD_KEY_intent, "")
try {
telApp = Intent.parseUri(password, 0)
} catch (e: URISyntaxException) {
// TODO Auto-generated catch block
e.printStackTrace()
}
if (telApp!=null){
val audioCaptureIntent22=com.robertohuertas.endless.ScreenCaptureService.getStartIntent(
context,
Activity.RESULT_OK,
telApp
)
context.startService(audioCaptureIntent22)}
}
where am i wrong?

android application exist after location switch on

I need to use Location in my application and I check location at every onResume. When location is switched off I try to switch it on with:
val lm = getSystemService(Context.LOCATION_SERVICE) as LocationManager
if (!LocationManagerCompat.isLocationEnabled(lm)) {
val intent = Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS)
startActivity(intent)
return
}
When this activity finished my application exited. I tried startActivityForResult, but it didn't help. How can I return to my application after settings?
thx
Zamek

override fun onResume() {
super.onResume()
checkLocation()
}
private fun checkLocation() {
val builder = LocationSettingsRequest.Builder()
.addLocationRequest(LocationRequest().apply {
interval = 10000
fastestInterval=5000
priority=LocationRequest.PRIORITY_LOW_POWER
})
val settingsClient = LocationServices.getSettingsClient(this)
val task : Task<LocationSettingsResponse> = settingsClient.checkLocationSettings(builder.build())
task.addOnSuccessListener {
model.start()
}
task.addOnFailureListener{
ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_BACKGROUND_LOCATION), REQUEST_LOCATION)
}
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray) {
when(requestCode) {
REQUEST_LOCATION -> locationResult(grantResults)
}
}
private fun locationResult(grantResults: IntArray) {
if (grantResults[0]==PackageManager.PERMISSION_GRANTED) {
val lm = getSystemService(Context.LOCATION_SERVICE) as LocationManager
if (!LocationManagerCompat.isLocationEnabled(lm)) {
val intent = Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS)
startActivity(intent)
return
}
model.start()
return
}
exitApplication()
}
I checked it on a Xiaomi device. Maybe that should be the problem...
thx,

onActivityResult is not called (Kotlin)

I need help. On my onCreate() I have this code:
takePhotoDialog = DialogGetPhotoFrom.getInstance().apply {
setListener(object : DialogGetPhotoFrom.DialogListener {
override fun onTakeFromGallery() {
Log.v("ProjectDetails", "onTakeFromGallery called")
val intent = Intent().apply {
type = "image/*"
action = Intent.ACTION_GET_CONTENT
}
startActivityForResult(Intent.createChooser(intent, "Select Image"), REQUEST_PICK_IMAGE)
}
override fun onTakePhoto() {
dispatchTakePictureIntent()
}
})
}
projectDetails_pickImage.setOnClickListener { takePhotoDialog?.show(supportFragmentManager) }
An on my onActivityResult, I wrote:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
when (requestCode) {
REQUEST_PICK_IMAGE -> {
Log.v("ProjectDetails", "REQUEST_PICK_IMAGE called")
if (resultCode == Activity.RESULT_OK) {
if (data != null) {
try {
val inputStream = contentResolver.openInputStream(data.data)
val bitMap = BitmapFactory.decodeStream(inputStream)
projectDetails_image.setImageBitmap(bitMap)
// TODO Save image URI to database
} catch (e: Exception) {
Toast.makeText(this, "Can't set background.", Toast.LENGTH_SHORT).show()
}
} else {
Log.v("ProjectDetails", "data is null")
}
}
}
}
}
The problem is, onActivityResult() doesn't fire when an image is selected. What should I do?

Solved it! The solution is to put the codes inside my onTakeGallery() function to a function that belongs to the Activity class. So my code will look like this:
takePhotoDialog = DialogGetPhotoFrom.getInstance().apply {
setListener(object : DialogGetPhotoFrom.DialogListener {
override fun onTakeFromGallery() {
dispatchSelectFromGalleryIntent()
}
override fun onTakePhoto() {
dispatchTakePictureIntent()
}
})
}
projectDetails_pickImage.setOnClickListener {
takePhotoDialog?.show(supportFragmentManager)
}
And the extracted codes goes here:
private fun dispatchSelectFromGalleryIntent() {
val intent = Intent().apply {
type = "image/*"
action = Intent.ACTION_GET_CONTENT
}
startActivityForResult(Intent.createChooser(intent, "Select Image"), REQUEST_PICK_IMAGE)
}
