一、Android現在申請許可權比較麻煩，在github查詢到一個比較好用的庫：AndPermission

依賴：

implementation 'com.yanzhenjie:permission:2.0.0-rc4'

在Fragment中要加上下面的語句，Activity中則可以省略，但我處理方式是都加上了，本身就是一個父類的重寫方法，activity中用不用看自己。

// 在Fragment中這句話不能註釋，否則Fragment接收不到獲取許可權的通知。
super.onRequestPermissionsResult(requestCode,permissions,grantResults);
 

獲取多個許可權：

// 先判斷是否有許可權。
if(AndPermission.hasPermission(this, Manifest.permission.READ_SMS)) {
    // 有許可權，直接do anything.
} else {
    // 申請許可權。
    AndPermission.with(this)
        .requestCode(100)
        .permission(Manifest.permission.WRITE_CONTACTS, Manifest.permission.READ_SMS)
        .send();
}

必須在初始化階段呼叫,例如onCreate()方法中

依賴：

compile 'com.tbruyelle.rxpermissions2:rxpermissions:[email protected]'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex.rxjava2:rxjava:2.0.5'

申請單個許可權：

RxPermissions rxPermissions = new RxPermissions(MainActivity.this);
        rxPermissions.request(Manifest.permission.READ_EXTERNAL_STORAGE)
                .subscribe(new Observer<Boolean>() {
                    @Override
                    public void onSubscribe(Disposable d) {
                        Toast.makeText(MainActivity.this, "應用需要讀寫許可權", Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onNext(Boolean value) {
                        if(value){
                            Toast.makeText(MainActivity.this, "同意權限", Toast.LENGTH_SHORT).show();
                        }else {
                            Toast.makeText(MainActivity.this, "拒絕許可權", Toast.LENGTH_SHORT).show();
                        }
                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onComplete() {

                    }
                });
 

同時申請多個許可權並且分別判斷許可權是否授予：

RxPermissions rxPermission = new RxPermissions(getActivity());
        rxPermission
                .requestEach(Manifest.permission.ACCESS_FINE_LOCATION,
                        Manifest.permission.WRITE_EXTERNAL_STORAGE,
                        Manifest.permission.READ_CALENDAR,
                        Manifest.permission.READ_CALL_LOG,
                        Manifest.permission.READ_CONTACTS,
                        Manifest.permission.READ_PHONE_STATE,
                        Manifest.permission.READ_SMS,
                        Manifest.permission.RECORD_AUDIO,
                        Manifest.permission.CAMERA,
                        Manifest.permission.CALL_PHONE,
                        Manifest.permission.SEND_SMS)
                .subscribe(new Consumer<Permission>() {
                    @Override
                    public void accept(Permission permission) throws Exception {
                        if (permission.granted) {
                            // 使用者已經同意該許可權
                            Log.d(TAG, permission.name + " is granted.");
                        } else if (permission.shouldShowRequestPermissionRationale) {
                            // 使用者拒絕了該許可權，沒有選中『不再詢問』（Never ask again）,那麼下次再次啟動時，還會提示請求許可權的對話方塊
                            Log.d(TAG, permission.name + " is denied. More info should be provided.");
                        } else {
                            // 使用者拒絕了該許可權，並且選中『不再詢問』
                            Log.d(TAG, permission.name + " is denied.");
                        }
                    }
                });

三、國產手機5.0、6.0許可權適配框架/編譯時註解框架）

引用

project 中的 build.gradle：

buildscript {
  // ...
}

allprojects {
  repositories {
    // 請新增如下一行
    maven { url 'https://jitpack.io' }
  }
}
app 中的 build.gradle：

dependencies {
  compile 'com.github.jokermonn:permissions4m:2.1.2-lib'
  annotationProcessor 'com.github.jokermonn:permissions4m:2.1.2-processor'
}

多個許可權申請：

Permissions4M.get(NormalFragment.this)
        .requestPermissions(Manifest.permission.BODY_SENSORS, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.READ_CALENDAR)

                    case LOCATION_CODE:
                        ToastUtil.show("地理位置許可權授權成功 in fragment with annotation");
                        break;
                    case SENSORS_CODE:
