Android sdk中提供了一个非常实用的tool - apkanalyzer, 该tool的路径是android_sdk/tools/bin/apkanalyzer

注意:该tool无法直接在window上运行,请下载安装git for windows: https://gitforwindows.org/, 并启动git bash


当然你也可以用Android Studio 工具:Analyze Your Build with APK Analyzer.

apkanalyzer用法


apkanalyzer [ global-options ] subject verb [ options ] apk-file [ apk-file2 ]

global-options是可选参数,后面再介绍。

subject参数用于指定你想要查询整个apk还是部分apk的信息,其取值可以是:

  • apk: 分析APK文件的属性,比如application ID, version code, and version name.
  • files: 分析APK文件里面的文件.
  • manifest: 分析APK文件里面的manifest.(注:这是我目前用的比较多的参数,之前是用AXMLPrinter2.jar)
  • dex: 分析APK之中的dex文件.
  • resources: 查看resource信息.

The verb is what you want to know about the subject. The subjects, verbs, and their options are described in Commands.

verb参数必须和subject结合使用。一般情况下我们只能指定分析一个apk文件,但是使用apk compare参数时,我们需要指定第二个apk文件。另外--human-readable可以简写成-h, 示例:


apkanalyzer - h apk file - size myapk . apk

Global options

OptionDescription
--human-readablePrints sizes in human-readable format.

常见用法

下面给出一些常见的用法

apk summary apk-filePrints the application ID, version code, and version name.

Example output:


     
com.myapp 5 1.1-beta
apk file-size apk-filePrints the total file size of the APK.
apk download-sizeapk-filePrints an estimate of the download size of the APK.
apk features [--not-required] apk-filePrints features used by the APK that trigger Play Store filtering . Add the --not-required option to include features marked as not required in the output.

Example output:


     
android.hardware.type.watch android.hardware.microphone implied: requested android.permission.RECORD_AUDIO permission
apk compare [optionsapk-fileapk-file2Compares the sizes of apk-file and apk-file2. You can include the following options:
  • --different-only: Print directories and files with differences.
  • --files-only: Do not print directory entries.
  • --patch-size: Show an estimate of the file-by-file patch instead of a raw difference.

Example output (old size / new size / size difference / path):

dex code --classclass [--methodmethod]Prints the bytecode of a class or method in smali format. The class name is required and prints the fully qualified class name to decompile. Add the --method option to specify the method to decompile. The format for the method decompile is name(params)returnType, for example, someMethod(Ljava/lang/String;I)V.

<think>我们正在讨论Android录音机APK的录音机制,特别是音频通道和调用方式。根据引用内容,我们可以总结以下几点: 1.权限要求:录音需要`RECORD_AUDIO`权限,存储需要`WRITE_EXTERNAL_STORAGE`权限(引用[1])。 2.使用`MediaRecorder`类进行录音:设置音频源(如麦克风)、输出格式、编码器、输出文件等(引用[2])。3.音频源(音频通道)设置:通过`setAudioSource`方法设置,常用的是`MediaRecorder.AudioSource.MIC`(麦克风)(引用[2])。4.其他可能的音频源:除了麦克风,Android还支持其他音频源,如语音通话、语音识别等(但标准录音机通常使用麦克风)。5.调用方式:通过Java代码初始化`MediaRecorder`,配置参数,然后开始录音(引用[2]和[4])。 具体到音频通道,Android系统提供了多个音频源(通道),定义在`MediaRecorder.AudioSource`中。其中: -`MIC`:主麦克风。 -`VOICE_UPLINK`:上行通话语音。- `VOICE_DOWNLINK`:下行通话语音。-`VOICE_CALL`:上下行通话语音混合。 -等等。但标准的录音机应用通常使用`MIC`作为音频源。实现步骤大致如下:1.创建`MediaRecorder`实例。 2.设置音频源(`setAudioSource`)。3.设置输出格式(`setOutputFormat`),如`THREE_GPP`。 4.设置音频编码器(`setAudioEncoder`),如`AMR_NB`。 5.设置输出文件路径(`setOutputFile`)。 6.准备(`prepare`)并开始(`start`)录音。此外,引用[3]提到了H5录音,但这不是原生Android的方式,而是Web方式。因此,Android录音机APK录音时使用的音频通道主要是麦克风(`MediaRecorder.AudioSource.MIC`),调用方式是通过`MediaRecorder`API。 下面我们按照要求生成回答。</think>### Android录音机APK录音机制分析 #### 一、音频通道与调用方式 Android录音机APK主要通过`MediaRecorder` API实现录音功能,核心音频通道为**麦克风输入通道**(MIC),调用方式如下: 1. **音频源设置** 使用`setAudioSource()`指定音频通道,标准录音机采用主麦克风通道: ```java mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); // 主麦克风通道 ``` 其他可选通道包括: - `VOICE_UPLINK`(上行通话) - `VOICE_DOWNLINK`(下行通话) - `VOICE_CALL`(双向通话) 2. **参数配置流程** 完整调用链包含四个关键步骤: ```java MediaRecorder recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); // 音频通道 recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); // 输出格式 recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); // 编码格式 recorder.setOutputFile("/sdcard/recording.3gp"); // 存储路径 ``` 3. **权限声明** 需在`AndroidManifest.xml`声明权限: ```xml <uses-permission android:name="android.permission.RECORD_AUDIO"/> <!-- 录音权限 --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <!-- 存储权限 --> ``` #### 二、底层实现机制 1. **音频流路径** $$ \text{麦克风} \xrightarrow{\text{ALSA驱动}} \text{AudioFlinger} \xrightarrow{\text{音频处理}} \text{MediaRecorder} $$ 2. **多通道支持** 通过修改音频源可实现多路录音(需硬件支持): ```java // 同时启用多麦克风(需API 23+) recorder.setAudioSource(MediaRecorder.AudioSource.UNPROCESSED); ``` 3. **音频格式兼容性** 常用格式对比如下: | 格式 | 码率 | 适用场景 | |---|---|---| | AMR_NB | 4.75-12.2 kbps | 语音通话 | | AAC_LC | 96-320 kbps | 高质量录音 | | OPUS | 6-510 kbps | 实时流媒体 | #### 三、适配注意事项 1. **Android 7.0+存储适配** 需使用`FileProvider`访问外部存储: ```xml <provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.fileprovider"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths"/> </provider> ``` 2. **运行时权限处理** Android 6.0+需动态申请权限: ```java ActivityCompat.requestPermissions( this, new String[]{Manifest.permission.RECORD_AUDIO}, REQUEST_CODE ); ``` > **关键引用**:标准录音机使用`MediaRecorder.AudioSource.MIC`作为主录音通道,通过`MediaRecorder` API实现音频捕获和编码存储[^2][^4]。
