Question

即使我尝试了所有可能找到的解决方案，也无法解决问题。我只想制作一把吉他调音器。当我执行时，收到此消息; “我的申请已停止”。我认为问题出在这里“audio.startRecording（）;”当我删除这条车道时，我不会停止消息。我为我的应用和虚拟设备尝试了api 15,25版本，甚至我的手机。你可以帮我解决一下这个问题吗？

这是我的代码：

package com.xxx.myapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.Activity;
import android.media.AudioFormat;
import android.media.AudioRecord;
import android.media.MediaRecorder;

public class MainActivity extends AppCompatActivity {
    private static final int sampleRate = 44100;
    private AudioRecord audio;
    private int bufferSize;
    private double lastLevel = 0;

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

    }

    protected void onResume() {
        super.onResume();
        bufferSize = AudioRecord
                .getMinBufferSize(sampleRate, AudioFormat.CHANNEL_IN_MONO,
                    AudioFormat.ENCODING_PCM_16BIT);
        audio = new AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate,
                AudioFormat.CHANNEL_IN_MONO,
                AudioFormat.ENCODING_PCM_16BIT, bufferSize);

        audio.startRecording();
        short[] buffer = new short[bufferSize];
        int bufferReadResult = audio.read(buffer, 0, bufferSize);
    }

}

清单：

    android:allowBackup="true"

        android:supportsRtl="true"
        android:theme="@style/AppTheme" >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
</manifest>

音频开始录制已停止 - 无法正常工作
