录制音频时 Firebase 模拟器测试失败
Firebase emulator tests fails when recording audio
音频录制在物理设备上工作得很好，但是，15-20%（5 个中有 1 个）firebase 模拟器测试失败。我们知道的唯一信息是这是本机崩溃。有没有大神能指教一下？
- 我们有权限，不用担心
我们使用类似这样的东西来按住录制按钮并在 5 秒后释放它
onView(withId(R.id.sound_button)).perform(pressAndHold());
waitforSec(5);
onView(withId(R.id.sound_button)).perform(release());
static class PressAndHoldAction implements ViewAction {
@Override
public Matcher<View> getConstraints() {
return isDisplayingAtLeast(90); // Like GeneralClickAction
}
@Override
public String getDescription() {
return "Press and hold action";
}
@Override
public void perform(final UiController uiController, final View view) {
if (sMotionEventDownHeldView != null) {
throw new AssertionError("Only one view can be held at a time");
}
float[] precision = Press.FINGER.describePrecision();
float[] coords = GeneralLocation.CENTER.calculateCoordinates(view);
sMotionEventDownHeldView = MotionEvents.sendDown(uiController, coords, precision).down;
// save view information and make sure release() is on same view
}
}
然后用这个
释放按钮
static class ReleaseAction implements ViewAction {
@Override
public Matcher<View> getConstraints() {
return isDisplayingAtLeast(90); // Like GeneralClickAction
}
@Override
public String getDescription() {
return "Release action";
}
@Override
public void perform(final UiController uiController, final View view) {
if (sMotionEventDownHeldView == null) {
throw new AssertionError("Before calling release(), you must call pressAndHold() on a view");
}
float[] coords = GeneralLocation.CENTER.calculateCoordinates(view);
MotionEvents.sendUp(uiController, sMotionEventDownHeldView, coords);
sMotionEventDownHeldView = null;
}
}

痛苦的5天终于搞定了！
问题是音频采样率和编码比特率。
初始化 MediaRecorder 对象时（开始前）
Emulator
audioRecorder.setAudioSamplingRate(8000);
audioRecorder.setAudioEncodingBitRate(32000);
Device
audioRecorder.setAudioSamplingRate(44100);
audioRecorder.setAudioEncodingBitRate(96000);
