Scala on Android: java.lang.NoSuchMethodError: java.lang.String.isEmpty
I've just released a new app on Android
I've optimized and obfuscated the code with proguard and tested extensively on my Android 2.3.3 phone. It works all right.
However, I keep getting really strange crash reports in the developer console, such as
java.lang.NoSuchMethodError: java.lang.String.isEmpty
Isn't String.isEmpty() a framework function on all Android devices?
There is TextUtils.isEmpty("your_String");, but haven't seen about your_string.isEmpty()
I found that your_string.isEmpty() works after 2.2 as it was added in 2.3 GingerBread. But, before that you can use TextUtils.isEmpty()

Call Recorder Not Working After Oreo Update

Closed 3 years ago.
Basically I've done call recording but it's not working up to Oreo.
I read an article in Wich google stop call recording in up to Oreo anyone have any idea how to record call in Android pie?
Code comments will be appreciated. Thanks
You can't.
The official call recording API was removed in Android 6.0 Marshmallow.
There was a workaround in native code around the root requirement, which worked until Android 8.1, but Google patched it in Android 9 Pie.
Call recording is not allowed from Android 6 Marshmallow. There was a workaround in native code around the root requirement, which worked until Android 8.1.

I searched a lot on internet but can't got right or reliable answer.
A native Android app can’t run on iOS. However their are many ways to build cross platform apps - of course they all have caveats and depending on the complexity of your app a native iOS app may be better.

I'm learning app development using android studio.
On build.gradle page i got stuck with one error i.e
"compile'com.android.support:appcompat-v7:25.2.0'"
under dependencies.
Do what it says... You need to use 25.2.0, not 23.0.0
This is especially needed because your compileSdk 25 should be using version 25 support library.
