When app not shows textviews(its finding a sensor. When cant find, giving info on textview like 'didnt found')
I created a pedometer app. It was working well on my emulator and my own android device. But when ı publish that app my friends said textviews are invisible. I examined that problem in code but didnt found a problem. Textviews are getting their text from sensor. Writing steps and calories, after some calculating. Why that problem showed up? What is the source of this problem? Why is this happening?

I found what is the problem. I was forgetting the add user permissions.
I Added to the Manifest.xml:
<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/>
onCreate Method:
if(ContextCompat.checkSelfPermission(this,
Manifest.permission.ACTIVITY_RECOGNITION) == PackageManager.PERMISSION_DENIED){
//ask for permission
requestPermissions(new String[]{Manifest.permission.ACTIVITY_RECOGNITION}, PHYISCAL_ACTIVITY);
}
