我收到此错误：
getDeviceId: Neither user 10111 nor current process has android.permission.READ_PHONE_STATE.
at android.os.Parcel.readException(Parcel.java:1599)
at android.os.Parcel.readException(Parcel.java:1552)
我已经把它放在了清单中。有关 Android 6.XX Marshmallow 设备有任何更改吗？我需要READ_PHONE_STATE权限才能获取设备的IMEI。 PLS。帮助
答案 0 :(得分：28)
是否在Android M上更改了权限。现在，在运行时请求权限，而不是Android M之前的安装时间。
您可以查看文档here
此版本引入了一种新的权限模型，用户现在可以在运行时直接管理应用程序权限。此模型为用户提供了更好的可见性和对权限的控制，同时简化了应用程序开发人员的安装和自动更新过程。用户可以单独为已安装的应用授予或撤消权限。
在针对Android 6.0（API级别23）或更高版本的应用中，请确保在运行时检查并请求权限。要确定您的应用是否已被授予权限，请调用新的checkSelfPermission（）方法。要请求权限，请调用新的requestPermissions（）方法。即使您的应用未定位到Android 6.0（API级别23），您也应该在新的权限模型下测试您的应用。
有关在应用中支持新权限模型的详细信息，请参阅使用系统权限。有关如何评估对应用程序的影响的提示，请参阅权限最佳实践。
要检查权限，您必须从github

我修改了@ Modge的代码， 在我的情况下，我需要请求IMEI权限，最好的方法是在运行时，所以我这样做：
/**
* A loading screen after AppIntroActivity.
*/
public class LoadingActivity extends BaseActivity {
private static final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 0;
private TextView loading_tv2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_loading);
//trigger 'loadIMEI'
loadIMEI();
/** Fading Transition Effect */
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
}
/**
* Called when the 'loadIMEI' function is triggered.
*/
public void loadIMEI() {
// Check if the READ_PHONE_STATE permission is already available.
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// READ_PHONE_STATE permission has not been granted.
requestReadPhoneStatePermission();
} else {
// READ_PHONE_STATE permission is already been granted.
doPermissionGrantedStuffs();
}
}
/**

* If the permission has been denied previously, a dialog will prompt the user to grant the
* permission, otherwise it is requested directly.

private void requestReadPhoneStatePermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.READ_PHONE_STATE)) {
// Provide an additional rationale to the user if the permission was not granted
// and the user would benefit from additional context for the use of the permission.

})
.setIcon(R.drawable.onlinlinew_warning_sign)

} else {
// READ_PHONE_STATE permission has not been granted yet. Request it directly.

我做了类似的事情：
if (checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE},
PERMISSIONS_REQUEST_READ_PHONE_STATE);
} else {
setDeviceImei();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
if (requestCode == PERMISSIONS_REQUEST_READ_PHONE_STATE
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
setDeviceImei();
}
}
private void setDeviceImei() {
mTelephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
//Code
.........
..............
}
我将如何获得我需要在运行时设置的权限列表..？

我们可以从https://developer.android.com/guide/topics/permissions/requesting.html
中找到所有危险的权限但是我认为在运行时检查并请求危险权限有点烦人。所以我只是用TARGET_SDK_VERSION = 22，一个懒惰的家伙（╰_╯）
