6.0 要单独的获取权限 

这里提供两种很简单的方法

• EasyPermition
• RxPermition

EasyPermition

dependencies {    //6.0 permition    compile 'pub.devrel:easypermissions:0.1.7'}

在启动的Activity添加如下代码

public class LoginActivity extends Activity implements EasyPermissions.PermissionCallbacks {    private static final int RC_CAMERA_PERM = 123;    private static final int RC_LOCATION_CONTACTS_PERM = 124;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_login);        requestPermissions();    }    private void requestPermissions() {    //要获取的权限        String[] perms = {Manifest.permission.INTERNET, Manifest.permission.WRITE_EXTERNAL_STORAGE};        if (EasyPermissions.hasPermissions(this, perms)) {            // Have permissions, do the thing!            Toast.makeText(this, "TODO: Location and Contacts things", Toast.LENGTH_LONG).show();        } else {            // Ask for both permissions            EasyPermissions.requestPermissions(this, getString(R.string.rationale_location_contacts),                    RC_LOCATION_CONTACTS_PERM, perms);        }    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);    }    @Override    public void onPermissionsGranted(int requestCode, List
     
       perms) {        Log.d(TAG, "onPermissionsGranted:" + requestCode + ":" + perms.size());    }    @Override    public void onPermissionsDenied(int requestCode, List
      
        perms) {        Log.d(TAG, "onPermissionsDenied:" + requestCode + ":" + perms.size());        EasyPermissions.checkDeniedPermissionsNeverAskAgain(this,                getString(R.string.rationale_ask_again),                R.string.setting, R.string.cancel, perms);    }}
      
     

RxPermition

dependencies {    compile 'com.tbruyelle.rxpermissions:rxpermissions:0.7.0@aar'}

同样在启动的Activity

public class LoginActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_login);        Observable
     
       request = RxPermissions.getInstance(Global.getContext())                .request(                        Manifest.permission.WRITE_EXTERNAL_STORAGE//文件读写/*                        Manifest.permission.READ_CONTACTS,//联系人                        Manifest.permission.READ_PHONE_STATE,                        Manifest.permission.ACCESS_FINE_LOCATION*/                );        request.subscribe(new Action1
      
       () {            @Override            public void call(Boolean granted) {                if (granted) {                    startActivity(new Intent(LoginActivity.this, MainActivity.class));                }            }        });    }}
      
     

针对RxPermition、写了个工具类 大家可以参考如下

public class PermissionsUtils {    public static Observable
     
       getFileAndContactsAndLocationGrant() {        Observable
      
        request = RxPermissions.getInstance(Global.getContext())                .request(                        Manifest.permission.WRITE_EXTERNAL_STORAGE,//文件读写                        Manifest.permission.READ_CONTACTS,//联系人                        Manifest.permission.READ_PHONE_STATE,                        Manifest.permission.ACCESS_FINE_LOCATION                );        return request;    }    public static Observable
       
         getCameraAndAudioGrant() {        Observable
        
          request = RxPermissions.getInstance(Global.getContext())                .request(                        Manifest.permission.CAMERA,//摄像头                        Manifest.permission.RECORD_AUDIO//麦克风                );        return request;    }    /**     * 引导到设置界面     * @param activity     * @param isFinish     */    @MainThread    public static void showPermissionDeniedDialog(final Activity activity, final boolean isFinish) {        DialogDeleteFriend dialog = new DialogDeleteFriend(activity, R.style.MyDialogBg);        dialog.show();        dialog.setIBtnListener(new IBtnClickListener() {            @Override            public void btnOk() {                Intent intent =  new Intent(Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);                activity.startActivity(intent);                if (isFinish) activity.finish();            }            @Override            public void btnCancle() {                if (isFinish) activity.finish();            }        });        dialog.updateType(DialogDeleteFriend.TYPE_TO_GRANTED);    }}
        
       
      
     

用法如下

/**     * 获取授权后加载登录信息，并进入登录界面 如果没获取到权限则引导到设置页面     */    private void getGrantedAndInitLoginInfo() {        rx.Observable
     
       grantObservable = PermissionsUtils.getFileAndContactsAndLocationGrant();        grantObservable.subscribe(new Action1
      
       () {            @Override            public void call(Boolean granted) {                if (granted) {                   //do somthing 6.0以后需要权限                } else {                    PermissionsUtils.showPermissionDeniedDialog(SplashActivity.this, true);                }            }        });    }
