在阅读设备ID等时,我在Android 6中收到错误。
在所有其他版本4.0,5.1等中如何正常工作。
这是我的代码:
public class MyDevIDS extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
PackageInfo pInfo = null;
try {
pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
} catch (NameNotFoundException e) {
e.printStackTrace();
}
String version = pInfo.versionName;
TextView versionText = (TextView) findViewById(R.id.tv7);
versionText.setText("Version : " + version);
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String imei_id = telephonyManager.getDeviceId();
TextView imei_idT = (TextView) findViewById(R.id.tv9);
String imei_idV = "<b><font color=#008000>" + imei_id + "</b></font>";
imei_idT.setText(Html.fromHtml("IMEI ID : " + imei_idV));
String device_id = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);
TextView device_idT = (TextView) findViewById(R.id.tv10);
String device_idV = "<b><font color=#008000>" + device_id + "</b></font>";
device_idT.setText(Html.fromHtml("Device ID : " + device_idV));
}
}
这是我得到的错误
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.devid/com.test.devid.MyDevIDS}: java.lang.SecurityException: getDeviceId: Neither user 10102 nor current process has android.permission.READ_PHONE_STATE.
我如何在清单中获得许可..但我需要在Android 6中提供运行时权限...
为此,我跟着this https://developer.android.com/training/permissions/requesting.html
但是我试过但它没有工作......
任何人都可以建议我如何在我的代码中使用运行时权限..

Android sdk已经从6.0版本开始实施了运行时权限功能。无论您在清单文件中获得许可,您都需要在访问之前检查该权限。
您可以使用hasSystemFeature(PackageManager.FEATURE_TELEPHONY)或getPhoneType()在运行时进行检查。
或者您可以按照我为相机许可
所做的格式进行检查 public void getCameraPermission(){
if (!checkPermission()) {
requestPermission();
}
}
private boolean checkPermission(){
int result = ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA);
if (result == PackageManager.PERMISSION_GRANTED){
return true;
} else {
return false;
}
}
private void requestPermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, Manifest.permission.CAMERA)){
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CAMERA}, PERMISSION_REQUEST_CODE);
} else {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CAMERA}, PERMISSION_REQUEST_CODE);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(MainActivity.this,"Permission granted",Toast.LENGTH_SHORT).show();
//store permission in shared pref
}
else {
Toast.makeText(MainActivity.this,"Permission denied",Toast.LENGTH_SHORT).show();
//store permission in shared pref
}
break;
}
}
