我正在使用以下代码来获取设备ID。
public static String getDeviceUuId(Activity context) {
String UUID = "";
String android_id = Secure.getString(context.getApplicationContext().getContentResolver(), Secure.ANDROID_ID);
final TelephonyManager tm = (TelephonyManager) context.getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);
if (tm != null) {
final String tmDevice, tmSerial, androidId;
tmDevice = "" + tm.getDeviceId();
tmSerial = "" + tm.getSimSerialNumber();
androidId = "" + Secure.getString(context.getContentResolver(), Secure.ANDROID_ID);
UUID deviceUuid = new UUID(androidId.hashCode(), ((long) tmDevice.hashCode() << 32) | tmSerial.hashCode());
UUID = deviceUuid.toString();
return UUID;
}
return UUID;
}
效果很好，但对于nexus 5（OS 6.0.1），我遇到了崩溃。以下是我的崩溃日志。

App专门在以下行崩溃。
tmDevice = "" + tm.getDeviceId();
它抱怨许可，但它已经在其他设备上添加并正常工作。

由于READ_PHONE_STATE在Android M（6.0）中被视为危险权限，因此您需要在运行时请求权限，然后在尝试获取活动中的UUID之前执行以下操作：
宣布
private static final int REQUEST_PHONE_STATE = 1;
然后在尝试获取UUID之前，您可以调用此方法：
private void checkForPhoneStatePermission(){
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(MainActivity.this,
Manifest.permission.READ_PHONE_STATE)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,
Manifest.permission.READ_PHONE_STATE)) {
// Show an explanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
showPermissionMessage();
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.READ_PHONE_STATE},
REQUEST_PHONE_STATE);
}
}
}else{
//... Permission has already been granted, obtain the UUID
getDeviceUuId(MainActivity.this);
}
}else{
//... No need to request permission, obtain the UUID
getDeviceUuId(MainActivity.this);
}
}
private void showPermissionMessage(){
new AlertDialog.Builder(this)
.setTitle("Read phone state")
.setMessage("This app requires the permission to read phone state to continue")
.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.READ_PHONE_STATE},
REQUEST_PHONE_STATE);
}
}).create().show();
}
然后将其添加到MainActivity类，该类处理权限请求的结果：
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch(requestCode){
case REQUEST_PHONE_STATE:
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
// .. Can now obtain the UUID
getDeviceUuId(MainActivity.this);
}else{
Toast.makeText(MainActivity.this, "Unable to continue without granting permission", Toast.LENGTH_SHORT).show();
}
break;
}
}

在marshmallow中，Android采用permissions行事的新方式，实际上您必须询问用户是否要授予对特定permission的访问权限。这就是为什么您的代码在低于6.0的版本上正常工作但不在6.0上工作的原因
