Android 6.0 之后动态权限申请

权限申请在Android 6.0 之前只是需要在 Manifest之中加一行代码就行,如下:

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

此处以打电话权限CALL_PHONE为例.

事实上权限分为两种

普通权限 :不威胁用户安全与隐私.

危险权限:威胁用户安全和隐私.

Android 6.0 之前都可以在Manifest文件中直接写就可以.
Android 6.0 之后 危险权限 需要动态申请.

依然以打电话作为例子,代码如下 :

public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();    }    private void initView() {        Button btnCall = (Button) findViewById(R.id.btn_main_call);        btnCall.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                //点击拨打电话是,因为是危险权限,所以需要动态申请.                //首先判断这个权限是否已被申请通过.                if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_DENIED) {                    //未通过,继续申请                    ActivityCompat.requestPermissions(MainActivity.this,new String[] {Manifest.permission.CALL_PHONE},1);                } else {                    //通过,直接拨打电话                    call();                }            }        });    }    private void call() {        Intent intent = new Intent(Intent.ACTION_CALL);        intent.setData(Uri.parse("tel:10086"));        startActivity(intent);    }    /**     * 通过查看返回值,判断是否授权成功     * @param requestCode     * @param permissions     * @param grantResults     */    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        switch (requestCode) {            case 1 :                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                    //成功                    call();                } else {                    //失败                    Toast.makeText(MainActivity.this,"授权失败",Toast.LENGTH_LONG).show();                }                break;            default:        }    }}

动态申请完毕,再贴一下危险权限列表,如果需要申请权限可以先查看是否是危险权限:

group:android.permission-group.CONTACTS
permission:android.permission.WRITE_CONTACTS
permission:android.permission.GET_ACCOUNTS
permission:android.permission.READ_CONTACTS

group:android.permission-group.PHONE
permission:android.permission.READ_CALL_LOG
permission:android.permission.READ_PHONE_STATE
permission:android.permission.CALL_PHONE
permission:android.permission.WRITE_CALL_LOG
permission:android.permission.USE_SIP
permission:android.permission.PROCESS_OUTGOING_CALLS
permission:com.android.voicemail.permission.ADD_VOICEMAIL

group:android.permission-group.CALENDAR
permission:android.permission.READ_CALENDAR
permission:android.permission.WRITE_CALENDAR

group:android.permission-group.CAMERA
permission:android.permission.CAMERA

group:android.permission-group.SENSORS
permission:android.permission.BODY_SENSORS

group:android.permission-group.LOCATION
permission:android.permission.ACCESS_FINE_LOCATION
permission:android.permission.ACCESS_COARSE_LOCATION

group:android.permission-group.STORAGE
permission:android.permission.READ_EXTERNAL_STORAGE
permission:android.permission.WRITE_EXTERNAL_STORAGE

group:android.permission-group.MICROPHONE
permission:android.permission.RECORD_AUDIO

group:android.permission-group.SMS
permission:android.permission.READ_SMS
permission:android.permission.RECEIVE_WAP_PUSH
permission:android.permission.RECEIVE_MMS
permission:android.permission.RECEIVE_SMS
permission:android.permission.SEND_SMS
permission:android.permission.READ_CELL_BROADCASTS

同一个group内的权限只要有一个被同意授权,权限组内其余的权限也会被默认授权
