Android6.0下的权限请求问题

运行一个应用的时候在其他系统上跑的是正常的，但是放到一个Andriod6.0的机子上就直接闪退了，

看了下日志，发现这句提示

ATAL EXCEPTION: mainProcess: ..****, PID: 12847java.lang.SecurityException: Sending SMS message: uid 10092 does not have android.permission.SEND_SMS

根据提示，应该是说我没有SEND_SMS权限，于是去检查了AndroidManifest.xml,发现已经加过了

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>  

为什么会出现这个问题呢，原因在于Android6.0后针对没有root的机器有更加严格的权限控制请求。具体权限列表如下：

ACCESS_COARSE_LOCATION
ACCESS_FINE_LOCATION
ADD_VOICEMAIL
BODY_SENSORS
CALL_PHONE
CAMERA
GET_ACCOUNTS
PROCESS_OUTGOING_CALLS
READ_CALENDAR
READ_CALL_LOG
READ_CELL_BROADCASTS
READ_CONTACTS
READ_EXTERNAL_STORAGE
READ_PHONE_STATE
READ_SMS
RECEIVE_MMS
RECEIVE_SMS
RECEIVE_WAP_PUSH
RECORD_AUDIO
SEND_SMS
USE_SIP
WRITE_CALENDAR
WRITE_CALL_LOG
WRITE_CONTACTS
WRITE_EXTERNAL_STORAGE

当然解决办法也有3种：

1）修改编译的版本为23.0以下 例如

targetSdkVersion 21

2）舍弃IMEI 的获取方式，更换为获取mac

TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);  
String imeiCode =null;  
try {  
    imeiCode=manager.getDeviceId();  
}catch(Exception e){  
    imeiCode=getMacAddress(context);  
} 

3. 使用checkSelfPermission和requestPermissions检查和请求权限

private static String[] PERMISSION= {Manifest.permission.READ_PHONE_STATE};  
private  boolean islacksOfPermission(String permission){  
    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.M){  
        return ContextCompat.checkSelfPermission(mContext, permission) ==  
                PackageManager.PERMISSION_DENIED;  
    }  
    return false;  
}  
  
@Override  
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {  
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);  
    if(requestCode==0x12){  
        setDeviceId();  
    }else{  
        finish();  
    }  
}  

Override  
   protected void onResume() {  
       super.onResume();  
       if(islacksOfPermission(PERMISSION[0])){  
           ActivityCompat.requestPermissions(this,PERMISSION,0x12);  
       }else{  
           setDeviceId();  
       }  
   }  
   private void setDeviceId(){  
       device_Id=getDeviceId();  
       app.setDeviceID(device_Id);  
   }  
   private String device_Id="";  
   private String getDeviceId(){  
       return  Utils.getDeviceImei(mContext);  
   }  

如果为了提升体验，也可以提示对话框让用户进行选择。
