我正在研究音频效果（这里是android api的audiofx），实时处理录音等，并制作一个可以发布的示例应用程序项目。

我想我快要完成我的项目了。我只是简单地引用了一个可以作为示例的应用程序，并且可以获得一些被反编译的代码片段，但在可以应用于MainActivity.

总共有 6 个错误

在这里，我揭示了可能导致错误的源代码

我跟踪了错误消息，所以我发现发生错误的代码部分如下

AudioFxActivity.java

1）关于第一个错误行：

PresetReverb localPresetReverb;
    if (bool1)
    {
      i = 0;
      localViewGroup.setVisibility(i);
      this.equalizer.setEnabled(bool1);
      this.bassBoost.setEnabled(this.bassSwitch.isChecked());
      j = this.reverbSpinner.getSelectedItemPosition();
      localPresetReverb = this.reverb;
      if (j <= 0) {
        break label136;                          // here 1st error occured
      }
    }
    label136:
    for (boolean bool2 = true;; bool2 = false)
    {
      localPresetReverb.setEnabled(bool2);
      this.reverb.setPreset((short)j);
      return;
      i = 8;
      break;
    }

2）关于第二个错误行：

for (boolean bool2 = true;; bool2 = false)
        {
          localPresetReverb.setEnabled(bool2);
          this.reverb.setPreset((short)j);         // here 2nd error occured
          return;
          i = 8;
          break;
        }

3）关于第三个错误行：

  localPresetReverb.setEnabled(bool2); // here 3rd error occured

4）关于第 4 个错误行：

do
        {
          return;
          this.audioForwarder.stop();   // here 4th error occured
          this.wakeLock.release();
          return;
          if (i == 0x7f070004)
          {
            boolean bool2 = this.eqSwitch.isChecked();
            this.equalizer.setEnabled(bool2);
            ViewGroup localViewGroup = this.eqSettings;
            if (bool2) {}
            for (int j = 0;; j = 8)
            {
              localViewGroup.setVisibility(j);
              return;
            }
          }
        } while (i != 0x7f070006);

5）关于第 4 个错误行：

boolean bool1 = this.bassSwitch.isChecked();    // here 5th error occured

6）关于第5个错误行：

for (boolean bool2 = true;; bool2 = false)
        {
          localPresetReverb.setEnabled(bool2);         // here 3rd error occured
          this.reverb.setPreset((short)j);
          return;
          i = 8;         // here 6th error occured
          break;
        }

我想这部分主要是关于错误的问题

do
{
  return;
  this.audioForwarder.stop();
  this.wakeLock.release();
  return;
  if (i == 0x7f070004)
  {
    boolean bool2 = this.eqSwitch.isChecked();
    this.equalizer.setEnabled(bool2);
    ViewGroup localViewGroup = this.eqSettings;
    if (bool2) {}
    for (int j = 0;; j = 8)
    {
      localViewGroup.setVisibility(j);
      return;
    }
  }
} while (i != 0x7f070006);

我认为这部分也可能是主要问题

PresetReverb localPresetReverb;
if (bool1)
{
  i = 0;
  localViewGroup.setVisibility(i);
  this.equalizer.setEnabled(bool1);
  this.bassBoost.setEnabled(this.bassSwitch.isChecked());
  j = this.reverbSpinner.getSelectedItemPosition();
  localPresetReverb = this.reverb;
  if (j <= 0) {
    break label136;
  }
}
label136:
for (boolean bool2 = true;; bool2 = false)
{
  localPresetReverb.setEnabled(bool2);
  this.reverb.setPreset((short)j);
  return;
  i = 8;
  break;
}

这个引用块是关于错误消息的

任何解决问题的答案将不胜感激。

祝你有快乐的日子。
