If you absolutely need a device to have a microphone, add a <uses-feature> element to your manifest asking for android.hardware.microphone .如果您绝对需要设备有麦克风，请在清单中添加一个<uses-feature>元素，要求android.hardware.microphone 。
If you could use a microphone if it exists, then add a <uses-feature> element to your manifest asking for android.hardware.microphone with android:required="false" .如果您可以使用麦克风（如果存在），则在清单中添加一个<uses-feature>元素，要求android.hardware.microphone和android:required="false" 。 Then, use PackageManager and hasSystemFeature() to check for android.hardware.microphone at runtime.然后，使用PackageManager和hasSystemFeature()在运行时检查android.hardware.microphone 。
