试图为android M实现摄像机权限获得没有虚拟方法checkSelfPermission

概述我以这种方式尝试实现摄像机权限： private void checkCameraPermissions() { if(checkCameraHardware(this)) { if (checkSelfPermission(Manifest.permission_group.camera) != PackageMan 我以这种方式尝试实现摄像机权限：

private voID checkCameraPermissions() {        if(checkCameraHarDWare(this)) {            if (checkSelfPermission(Manifest.permission_group.camera)                    != PackageManager.PERMISSION_GRANTED) {                Crashlytics.log("Requesting camera permission");                // Should we show an explanation?                if (shouldShowRequestPermissionRationale(                        Manifest.permission_group.camera)) {                    // Explain to the user why we need to use the camera                    showRationaleForCameraUse();                }                requestPermissions(new String[]{Manifest.permission_group.camera},Constants.MY_PERMISSIONS_REQUEST_CAMERA_GROUP);                // MY_PERMISSIONS_REQUEST_CAMERA_GROUP is an                // app-defined int constant            } else {                startApp();            }        }else{            showNoCameraAvailableAlert();        }    }@OverrIDe    public voID onRequestPermissionsResult(int requestCode,String permissions[],int[] grantResults) {        switch (requestCode) {            case Constants.MY_PERMISSIONS_REQUEST_CAMERA_GROUP: {                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {                    // permission was granted,yay!                    // start the app                    startApp();                } else {                    // permission denIEd,boo!                    // leav the app!                    showNoCameraAvailableAlert();                }                return;            }            // other 'switch' lines to check for other            // permissions this app might request        }    }

并得到以下错误：

java.lang.NoSuchMethodError: No virtual method checkSelfPermission(Ljava/lang/String;)I in class lim/emu/app/emu/app/vIEw/splash/SplashActivity; or its super classes (declaration of 'im.emu.app.emu.app.vIEw.splash.SplashActivity' appears in /data/app/im.emu.app.emu.test-1/base.apk)            at im.emu.app.emu.app.vIEw.splash.SplashActivity.checkCameraPermissions(SplashActivity.java:74)            at im.emu.app.emu.app.vIEw.splash.SplashActivity.onCreate(SplashActivity.java:52)            at androID.app.Activity.performCreate(Activity.java:5977)            at androID.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1105)            at androID.app.ActivityThread.performlaunchActivity(ActivityThread.java:2258)            at androID.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2367)            at androID.app.ActivityThread.access0(ActivityThread.java:148)            at androID.app.ActivityThread$H.handleMessage(ActivityThread.java:1283)            at androID.os.Handler.dispatchMessage(Handler.java:102)            at androID.os.Looper.loop(Looper.java:135)            at androID.app.ActivityThread.main(ActivityThread.java:5274)            at java.lang.reflect.Method.invoke(Native Method)            at java.lang.reflect.Method.invoke(Method.java:372)            at com.androID.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:909)            at com.androID.internal.os.ZygoteInit.main(ZygoteInit.java:704)08-30 16:34:10.801  17087-17357/im.emu.app.emu.test I/Fabric﹕ Crashlytics report upload complete: 55E30629033A-0001-42BF-296ED8AC703A.cls

任何想法如何解决这个问题？
附：如果需要更多的信息请问

解决方法 您应该运行运行先前版本的设备上的代码.你必须使用ContextCompat.checkSelfPermission(). 总结
