android - ACCESS_COARSE_LOCATION android 权限问题

Question

您好，我在 Android 应用程序中遇到 ACCESS_COARSE_LOCATION 权限问题。我已将权限添加到 list 中:

    <!-- Required for Nearby Connections API -->
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

并在我的 onStart() 方法中请求了权限:

    override fun onStart() {
    super.onStart()
    requestPermissions(arrayOf(
        Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION),
        REQUEST_CODE_PERMISSIONS)
}

并检查它是否被授予:

        if (ContextCompat.checkSelfPermission(
            this,
            Manifest.permission.ACCESS_COARSE_LOCATION
        ) == PackageManager.PERMISSION_GRANTED
    ) {

        mConnectionsClient.startDiscovery(
            SERVICE_ID,
            mEndpointDiscoveryCallback,
            DiscoveryOptions.Builder().setStrategy(Strategy.P2P_STAR).build()
        )
            .addOnSuccessListener {
                debug("Success startDiscovery: $it")
            }
            .addOnFailureListener {
                debug("Failure startDiscovery: $it")
            }
    }

同样，当我检查是否授予权限时，它说是，但仍然显示错误:

Failure startDiscovery: com.google.android.gms.common.api.ApiException: 8034: MISSING_PERMISSION_ACCESS_COARSE_LOCATION

有人知道问题出在哪里吗？

Answer 1

确保您的测试设备没有在设置中全局关闭“定位”。

即使您请求并随后检查以确保您已被授予所有正确的权限以开始实际调用发现

Nearby.getConnectionsClient(...).startDiscovery(...)

还是会回来

com.google.android.gms.common.api.ApiException: 8034: MISSING_PERMISSION_ACCESS_COARSE_LOCATION
