Android

Question

我的应用程序是通过 Google Play 或 USB 安装的（与所有其他通用应用程序一样使用麦克风、摄像头），默认情况下应用程序获取 "No permission allowed".

因此，在全新安装后它永远无法运行。

除非有人手动进入应用程序设置并进行更改。

我做错了什么？为什么会导致默认进入拒绝权限模式？

AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CAMERA" />

Answer 1

从 Android Marshmallow (6.0) 开始，您必须在运行时请求权限。这样用户可以手动接受或拒绝您需要的每个权限。
有关实现权限的帮助，请参阅 Android documentation。

这可以防止应用程序在未经用户同意的情况下'secretly'使用私人设备和用户信息。

Answer 2

从 Android M 开始，您需要为所需的每个权限请求运行时权限。

请求联系人权限的示例是：-

if (ContextCompat.checkSelfPermission(thisActivity,
            Manifest.permission.READ_CONTACTS)
    != PackageManager.PERMISSION_GRANTED) {

if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
        Manifest.permission.READ_CONTACTS)) {

} else {

    ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.READ_CONTACTS},
            MY_PERMISSIONS_REQUEST_READ_CONTACTS);
 }
}

Answer 3

您需要在代码中为Marshmallow及以上设备设置权限。插件也提供此功能。

Sample reference mentioning the same 即使提到了 ionic，在 cordova 项目中也需要使用相同的方法

要获得权限状态，请复制如下。

cordova.plugins.diagnostic.getPermissionAuthorizationStatus(function (status) {
  console.log(status);
  switch (status) {
    case cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED:
      //call the target method
      break;
    case cordova.plugins.diagnostic.runtimePermissionStatus.NOT_REQUESTED:
      setPermission();
      break;
    case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED:
      setPermission();
      break;
    case cordova.plugins.diagnostic.runtimePermissionStatus.DENIED_ALWAYS:
      setPermission();
      break;
  }
}, this.errorCallback, cordova.plugins.diagnostic.runtimePermission.ACCESS_COARSE_LOCATION);

并请求授权

function setPermission() {
  cordova.plugins.diagnostic.requestLocationAuthorization(function (status) {
    switch (status) {
      case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
        break;
      case cordova.plugins.diagnostic.permissionStatus.DENIED:
        break;
      case cordova.plugins.diagnostic.permissionStatus.GRANTED:
        //TODO : Call native plugin.
        break;
      case cordova.plugins.diagnostic.permissionStatus.GRANTED_WHEN_IN_USE:
        break;
    }
  }, function (error) { }, cordova.plugins.diagnostic.locationAuthorizationMode.ALWAYS);
}

Android - 安装我的应用程序时，默认设置 "No permission allowed"？

Android - when ever my app is installed, by default "No permission allowed" is set?
