Android6.0开始引入了运行时权限申请，类似IOS。
比如电话权限：
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
binding.makeCall.setOnClickListener {
val permission = ContextCompat.checkSelfPermission(this, android.Manifest.permission.CALL_PHONE)
if (permission != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
arrayOf(android.Manifest.permission.CALL_PHONE), 1)
} else {
call()
}
}
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
when (requestCode) {
1 -> {
if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
call()
} else {
Toast.makeText(this, "You denied the permission", Toast.LENGTH_SHORT).show()
}
}
}
}
private fun call() {
try {
val intent = Intent(Intent.ACTION_CALL)
intent.data = Uri.parse("tel:10086")
startActivity(intent)
} catch (e: SecurityException) {
e.printStackTrace()
}
}
}
AndroidManifest.xml
<uses-feature
android:name="android.hardware.telephony"
android:required="false" />
<uses-permission android:name="android.permission.CALL_PHONE" />
