android-10.0

In my VPN application up until Android-9, it was possible to read the /proc/net/tcp files from apps targeting API level < 28. Access from apps no longer seems to work in Android Q. I'm getting an error /proc/net/tcp: open failed: EACCES (Permission denied) while trying to read the file. In Android-Q privacy change google has addressed Restriction on access to /proc/net filesystem And I think ConnectivityManager.getConnectionOwnerUid() can be used if the apps compileSDK version is 29. But unfortunately at the moment, I can't change my compileSDK version but I updated the targetSDK version to

Background I've noticed that in WifiManager class there is a function called addNetwork , that might be useful if I want to restore or save networks information (network name AKA SSID, together with the password and the type), so that I could also connect to it. The problem I can't find much information about how to do such a thing. I've seen various examples on StackOverflow, and if I target Android API 28 (or below), I indeed succeed to make it add a network and even connect to it. When targeting Android 29 (Android Q), however, it fails to add the network. What I've found Since I'm trying

1)Target set to Android Q with ""android.permission.WRITE_EXTERNAL_STORAGE"" 2) use getExternalStorageDirectory or getExternalStoragePublicDirectory and FileOutputStream(file) saving file throws java.io.FileNotFoundException: /storage/emulated/0/myfolder/mytext.txt: open failed: ENOENT (No such file or directory) 3) use getExternalFilesDir api and saving is success but wont show up even after MediaScannerConnection.scanFile. /storage/emulated/0/Android/data/my.com.ui/files/Download/myfolder/mytext.txt What is best way to copy file from internal memory to SDCARD in android Q and refresh. In

Once I switch my target api to 'Q' I cannot install the APK on Android Q Emulator. I get error: Failed to finalize session : INSTALL_FAILED_INVALID_APK: Failed to extract native libraries, res=-2 Android Studio (v3.3.2) recommends I uninstall apk first. I tried uninstalling apk and I still get the same error. App work if I downgrade target api to 28. This happens because of an issue with zipalign, see - https://issuetracker.google.com/issues/37045367 . You need to set extractNativeLibs in your Application Tag on AndroidManifest.xml <application android:allowBackup="false" android:label="

My application works fine from Android 4.3 until Android 9 Pie, but my application doesn't work on Android 10 (Q API 29) and crashes. This is my logcat - why this is happening? java.lang.RuntimeException: Unable to start activity ComponentInfo{ir.mahdi.circulars/ir.mahdi.circulars.MainActivity}: android.view.InflateException: Binary XML file line #17 in ir.mahdi.circulars:layout/abc_screen_simple: Binary XML file line #17 in ir.mahdi.circulars:layout/abc_screen_simple: Error inflating class androidx.appcompat.widget.FitWindowsLinearLayout and this is my mainActivity.xml <?xml version="1.0"

Background I know that we can get the network usage (total bandwidth used of mobile&Wifi so far, from some specific time) of a specified app by using something like that (asked in the past, here ) : private final static int[] NETWORKS_TYPES = new int[]{ConnectivityManager.TYPE_WIFI, ConnectivityManager.TYPE_MOBILE}; long rxBytes=0L, txBytes=0L; final TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); final String subscriberId = telephonyManager.getSubscriberId(); final ApplicationInfo applicationInfo = context.getPackageManager()

In Android Q, users can enable full screen gesture mode. I want to detect whether the device in full screen gesture mode or not. I can't find anything in documentation. How to do it programmatically at run time? Java or kotlin language answer is OK. Any official API or workaround... According to docs, you can get area of gesture space using getSystemGestureInsets() : https://developer.android.com/reference/android/view/WindowInsets.html#getSystemGestureInsets() If it's zero, then it's disabled ViewCompat.setOnApplyWindowInsetsListener(view, (v, insets) -> { if (insets.getSystemGestureInsets()

Since setWifiEnabled is deprecated on Android 10, how does one programatically enable wifi on Android 10 devices? Is it not possible to programatically enable wifi at all on Android 10+ (SDK 29) ? No, This is not possible to enable or disable Wi-Fi programmatically from Android-10 API level 29 [ Until google provides an alternative solution ]. For applications targeting Build.VERSION_CODES.Q or above, this API will always return false and will have no effect. If apps are targeting an older SDK ( Build.VERSION_CODES.P or below), they can continue to use this API. There is an issue 128554616
