Android 6.0运行时权限

Android 6.0运行时权限

作者: 有没有口罩给我一个 | 来源:发表于2018-03-17 01:31 被阅读0次

在Android 6.0以前,我们安装App时会列出安装的App的访问权限,而且只有安装时才会出现 一次,一旦我们同意了并安装App,这个App就可以在用户不知道的情况下访问权限内的所有东西,所以Google在Android6.0时增加了权限运行时询问用户授权权限,Google将权限分为Normal Permission和Dangerous Permission

Normal Permission

  • ACCESS_LOCATION_EXTRA_COMMANDS
  • ACCESS_NETWORK_STATE
  • ACCESS_NOTIFICATION_POLICY
  • ACCESS_WIFI_STATE
  • BLUETOOTH
  • BLUETOOTH_ADMIN
  • BROADCAST_STICKY
  • CHANGE_NETWORK_STATE
  • CHANGE_WIFI_MULTICAST_STATE
  • CHANGE_WIFI_STATE
  • DISABLE_KEYGUARD
  • EXPAND_STATUS_BAR
  • GET_PACKAGE_SIZE
  • INSTALL_SHORTCUT
  • INTERNET
  • KILL_BACKGROUND_PROCESSES
  • MODIFY_AUDIO_SETTINGS
  • NFC
  • READ_SYNC_SETTINGS
  • READ_SYNC_STATS
  • RECEIVE_BOOT_COMPLETED
  • REORDER_TASKS
  • REQUEST_IGNORE_BATTERY_OPTIMIZATIONS
  • REQUEST_INSTALL_PACKAGES
  • SET_ALARM
  • SET_TIME_ZONE
  • SET_WALLPAPER
  • SET_WALLPAPER_HINTS
  • TRANSMIT_IR
  • UNINSTALL_SHORTCUT
  • USE_FINGERPRINT
  • VIBRATE
  • WAKE_LOCK
  • WRITE_SYNC_SETTINGS

Dangerous Permission

Dangerous Permission 是以分组的形式给出

  • CALENDAR(日历)
    READ_CALENDAR
    WRITE_CALENDAR
  • CAMERA(相机)
    CAMERA
    CONTACTS(联系人)
    READ_CONTACTS
    WRITE_CONTACTS

    ACCESS_FINE_LOCATION
    ACCESS_COARSE_LOCATION
  • MICROPHONE(麦克风)
    RECORD_AUDIO
  • PHONE(手机)
    READ_PHONE_STATE
    CALL_PHONE
    READ_CALL_LOG
    WRITE_CALL_LOG
    ADD_VOICEMAIL
    USE_SIP
    PROCESS_OUTGOING_CALLS
  • SENSORS(传感器)
    BODY_SENSORS
  • SMS(短信)
    SEND_SMS
    RECEIVE_SMS
    READ_SMS
    RECEIVE_WAP_PUSH
    RECEIVE_MMS
  • STORAGE(存储卡)
    READ_EXTERNAL_STORAGE
    WRITE_EXTERNAL_STORAGE

举个栗子

public class MainActivity extends AppCompatActivity {
private static final int PERMOSSION_REQUEST_PHONE = 1;
private Button btn_call;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btn_call = findViewById(R.id.button);
    btn_call.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            call();
        }
    });
}

public void call() {
    //检查App是否有permission.CALL_PHONE 的权限
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        //如果没有permission.CALL_PHONE 的权限,就申请权限
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission_group.PHONE}, PERMOSSION_REQUEST_PHONE);
    } else {
        callPhone();
    }
}

public void callPhone() {
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" + "10086"));
    try {
        startActivity(intent);
    } catch (SecurityException e) {
        e.printStackTrace();
    }
}

//申请权限的回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (PERMOSSION_REQUEST_PHONE == requestCode) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            callPhone();
        } else {
            if (!ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CALL_PHONE)) {
                AlertDialog alertDialog = new AlertDialog.Builder(this)
                        .setMessage("该功能需要访问电话权限,不开启将无法正常使用!")
                        .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {

                            }
                        }).create();
                alertDialog.show();
            }
            Toast.makeText(this, "权限被拒绝", Toast.LENGTH_SHORT).show();
        }
        return;
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

call方法首先判断当前App是否有permission.CALL_PHONE权限,如果有直接调用callPhone方法打电话,如果没有该权限,则弹出提示框进行申请权限,onRequestPermissionsResult就是申请权限的回调,如果用户允许,则调用callPhone方法;如果用户拒绝。就弹出Toast实现权限被拒绝,需要注意的是:如果我们选择允许下一次就不会弹出申请权限对话框了;如果我们拒绝,则下一次还会演出弹出提示框,只不过会多出一个“不再询问”选择按钮,如果我们选择该选项,下一次就不会弹出对话框了,而是直接调用onRequestPermissionsResult方法,所以需要ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CALL_PHONE),来解析权限的情况;

最后建议使用已经封装好的库PermissionDispatcher

使用教程官方讲的很详细也很简单:

//必需的注解,它用来注册一个Activity或Fragment,使用方法他们可以处理权限
@RuntimePermissions
public class MainActivity extends AppCompatActivity {

private static final int PERMOSSION_REQUEST_PHONE = 1;
private Button btn_call;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn_call = findViewById(R.id.button);

    btn_call.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            call();
        }
    });
}

public void call() {
    callPhone();
}

@NeedsPermission(android.Manifest.permission.CALL_PHONE)
//在需要权限的地方注释
public void callPhone() {
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" + "10086"));
    try {
        startActivity(intent);
    } catch (SecurityException e) {
        e.printStackTrace();
    }
}

//提示用户为何开启此权限
@OnShowRationale(android.Manifest.permission.CALL_PHONE)
public void showWhy(final PermissionRequest request) {
    android.app.AlertDialog alertDialog = new android.app.AlertDialog.Builder(this)
            .setMessage("该功能需要访问电话权限,不开启将无法正常使用!")
            .setPositiveButton("知道了", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    request.proceed();//再次请求
                }
            }).create();
    alertDialog.show();
}

//用户选择拒绝的提示
@OnPermissionDenied(android.Manifest.permission.CALL_PHONE)
public void showDenied() {
    Toast.makeText(this, "用户选择拒绝的提示", Toast.LENGTH_SHORT).show();
}

@OnNeverAskAgain(android.Manifest.permission.CALL_PHONE)
void showNotAsk() {
    android.app.AlertDialog alertDialog = new android.app.AlertDialog.Builder(this)
            .setMessage("该功能需要访问电话权限,不开启将无法正常使用!")
            .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                }
            }).create();
    alertDialog.show();
    }
}

最后生成XXXPermissionDispatcher,所有工作都交给它完成就好了;
其实第三方封装权限处理的库,大家有兴趣可以分享;
