Android studio中Webview应用的MIC访问问题

Question

我建立了一个web视图应用程序。它是一个在线学费应用程序。所以，每天都有一个实时视频课程。所以需要许可才能使用他们的麦克风。请帮助我们摆脱这个问题。输入图片描述

Answer 1

Android 6.0及以上版本在安装时没有任何权限。因此，您需要在运行时请求许可。可能，您还没有授予应用程序的音频录制权限。
要解决此问题，请转到位于/app/src/main/AndroidManifest.xml的AndroidManifest.xml文件并添加以下权限。

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

您需要在应用程序块之外添加此权限。

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

Answer 2

Iam already added those permission.

<uses-permission android:name="android.permission.MICROPHONE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-feature android:name="android.hardware.audio.low_latency" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-feature android:name="android.hardware.audio.pro" />
<uses-feature android:name="android.hardware.microphone"/>
and code here.

if(checkAndRequestPermissions()){
//all permission granted
}else{
//require all permission.
}
}

private boolean checkAndRequestPermissions() {
int camerapermission = ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA);
int phonestate = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);
int location = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
int recordaudio = ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO);
int modifyAudio = ContextCompat.checkSelfPermission(this, Manifest.permission.MODIFY_AUDIO_SETTINGS);
int caputureaudio = ContextCompat.checkSelfPermission(this, Manifest.permission.CAPTURE_AUDIO_OUTPUT);
int permissionLocation = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

List<String> listPermissionsNeeded = new ArrayList<>();
if (camerapermission != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.CAMERA);
}
if (phonestate != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.READ_PHONE_STATE);
}
if (location != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (recordaudio != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.RECORD_AUDIO);
}
if (modifyAudio != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.MODIFY_AUDIO_SETTINGS);
}
if (caputureaudio != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.CAPTURE_AUDIO_OUTPUT);
}
if (permissionLocation != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
