有关6.0权限应用启动一次性设置问题

做有关6.0权限的问题只需要在mainactiviy中一次性把所有的权限都让用户确认一遍就行。

public class MainActivity extends AppCompatActivity {

    private static final String TAG ="MainActivity" ;
    private boolean isRequireCheck; // 是否需要系统权限检测
    private PermissionsChecker mPermissionsChecker;//检查权限
    //危险权限（运行时权限）

            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.RECORD_AUDIO

    };

        isRequireCheck = true;
        versionCode = Build.VERSION.RELEASE;
        substring = versionCode.substring(0, 1);
        L.d(TAG,"我是版本号-==="+ versionCode);
    }

前提还要在AndroidMaifest文件中把相应的权限加上
