本文实例讲述了Android编程检测手机录音权限是否打开的方法。分享给大家供大家参考，具体如下：

6.0之前的权限检测只是检测到是否在清单文件中注册

Boolean flag = (PackageManager.PERMISSION_GRANTED ==

pm.checkPermission("android.permission.RECORD_AUDIO", "包名"));

Boolean flag = PermissionChecker.checkSelfPermission(this, Manifest.permission.)== PermissionChecker.PERMISSION_GRANTED;

if (flag){

ToastUtil.showMessage("有权限");

} else {

ToastUtil.showMessage("无权限");

return;

}

在6.0系统一下 无论是关闭或者打开app的录音权限都能获取到权限，6.0以上则正常，后来发现是6.0以后google加强了权限管理

public class CheckPermissionUtils {

/**

*获取app的录音权限是否打开

*android 6.0version以上 传统方法不适合 以此兼容

* @param context

*/

public static Boolean isHasAudioRecordPermission(Context context) {

// 音频获取源

int audioSource = MediaRecorder.AudioSource.MIC;

// 设置音频采样率，44100是目前的标准，但是某些设备仍然支持22050，16000，11025

int sampleRateInHz = 44100;

// 设置音频的录制的声道CHANNEL_IN_STEREO为双声道，CHANNEL_CONFIGURATION_MONO为单声道

int channelConfig = AudioFormat.CHANNEL_IN_STEREO;

// 音频数据格式:PCM 16位每个样本。保证设备支持。PCM 8位每个样本。不一定能得到设备支持。

int audioFormat = AudioFormat.ENCODING_PCM_16BIT;

// 缓冲区字节大小

int bufferSizeInBytes = 0;

bufferSizeInBytes = AudioRecord.getMinBufferSize(sampleRateInHz,

channelConfig, audioFormat);

AudioRecord audioRecord = new AudioRecord(audioSource, sampleRateInHz,

channelConfig, audioFormat, bufferSizeInBytes);

//开始录制音频

try{

// 防止某些手机崩溃，例如联想

audioRecord.startRecording();

}

catch (IllegalStateException e){

e.printStackTrace();

}

/**

* 根据开始录音判断是否有录音权限

*/

if (audioRecord.getRecordingState() != AudioRecord.RECORDSTATE_RECORDING) {

return false;

}

audioRecord.stop();

audioRecord.release();

audioRecord = null;

return true;

}

}

最后一种，测试没问题。

public class CheckPermissionUtils {

private static final String TAG = "CheckPermissionUtils";

private static CheckPermissionUtils checkPermissionUtils = new CheckPermissionUtils();

static final int SAMPLE_RATE_IN_HZ = 44100;

static final int BUFFER_SIZE = AudioRecord.getMinBufferSize(

SAMPLE_RATE_IN_HZ, AudioFormat.CHANNEL_IN_DEFAULT,

AudioFormat.ENCODING_PCM_16BIT);

private AudioRecord mAudioRecord;

Boolean isGetVoiceRun;

private Object mLock;

private int count=0;

private Boolean isHasPermission;

private CheckPermissionUtils() {

mLock = new Object();

}

public static CheckPermissionUtils getinstance() {

if (checkPermissionUtils == null) {

checkPermissionUtils = new CheckPermissionUtils();

}

return checkPermissionUtils;

}

public Boolean isHasAudioRecordingPermission(Context context) {

isHasPermission=false;

count=0;

mAudioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,

SAMPLE_RATE_IN_HZ, AudioFormat.CHANNEL_IN_DEFAULT,

AudioFormat.ENCODING_PCM_16BIT, BUFFER_SIZE);

if (mAudioRecord == null) {

Log.e("sound", "mAudioRecord初始化失败");

}

isGetVoiceRun = true;

try {

// new Thread(new Runnable() {

// @Override

// public void run() {

mAudioRecord.startRecording();

short[] buffer = new short[BUFFER_SIZE];

while (isGetVoiceRun) {

count++;

if (count++>10) {

isGetVoiceRun=false;

}

//r是实际读取的数据长度，一般而言r会小于buffersize

int r = mAudioRecord.read(buffer, 0, BUFFER_SIZE);

long v = 0;

// 将 buffer 内容取出，进行平方和运算

for (int i = 0; i < buffer.length; i++) {

v += buffer[i] * buffer[i];

}

// 平方和除以数据总长度，得到音量大小。

double mean = v / (double) r;

double volume = 10 * Math.log10(mean);

Log.d(TAG, "-------分贝值:" +volume+"----v"+v+"------r"+r );

if (v>0&&r>0) {

//有录音

isHasPermission=true;

return isHasPermission;

}

// 大概一秒十次

synchronized (mLock) {

try {

mLock.wait(5);

}

catch (InterruptedException e) {

e.printStackTrace();

}

}

}

mAudioRecord.stop();

mAudioRecord.release();

mAudioRecord = null;

// }

//}).start();

}

catch (Exception e) {

}

return isHasPermission;

}

}
