如果设备在使用 getLine1Number()时尝试获取电话号码时运行Android 6.0或更高版本:
java.lang.SecurityException:需要READ_PHONE_STATE:用户10184和当前进程都没有android.permission.READ_PHONE_STATE。 这是出来的。
我宣布许可为:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
答案 0 :(得分:19)
在Android 6.0中,您需要明确要求用户授予权限。只是在清单中宣布它是不够的。
文档中的article是开始学习新模型的好地方,但我会做一个简短的总结。
每次执行需要&#34;危险许可的操作时,&#34;您需要检查当前是否已授予权限,因为用户可以随时撤消该权限。
可以使用char ** => const char**
方法完成此操作。
checkSelfPermission
您可以使用if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// We do not have this permission. Let's ask the user
}
方法申请权限,
requestPermissions
其中ActivityCompat.requestPermissions(thisActivity, new String[]{Manifest.permission.READ_PHONE_STATE}, PERMISSION_READ_STATE);
是您定义的常量整数,以便稍后检入回调方法。
然后,您将覆盖活动中的PERMISSION_READ_STATE
,并查看是否已授予权限。如果是的话,你可以继续进行危险的行动。

public class MainActivity extends AppCompatActivity {

private static final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 0;

loadIMEI();

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE},
MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
}
} else {
TelephonyManager mngr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
IMEI = mngr.getDeviceId();
device_unique_id = Settings.Secure.getString(this.getContentResolver(),
Settings.Secure.ANDROID_ID);
textView.setText(device_unique_id+"----"+mngr.getDeviceId());
// READ_PHONE_STATE permission is already been granted.
Toast.makeText(this,"Alredy granted",Toast.LENGTH_SHORT).show();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,@NonNull int[] grantResults) {
if (requestCode == MY_PERMISSIONS_REQUEST_READ_PHONE_STATE) {
