Android 开发常用的ADB命令，以及相关常见问题解决方案，本文会不断维护；

Android 检查权限

private fun checkRoot(): Boolean {
        val binPath = "/system/bin/su"
        val xBinPath = "/system/xbin/su"
        if (File(binPath).exists() && isCanExecute(binPath)) {
            return true
        }
        if (File(xBinPath).exists() && isCanExecute(xBinPath)) {
            return true
        }
        return false
}

private fun isCanExecute(filePath: String): Boolean {
        var process: Process? = null
        try {
            process = Runtime.getRuntime().exec("ls -l $filePath")
            val bufferedReader = BufferedReader(InputStreamReader(process.inputStream))
            val readLine: String = bufferedReader.readLine()
            if (readLine.length >= 4) {
                val flag = readLine[3]
                if (flag == 's' || flag == 'x')
                    return true
            }
        } catch (e: IOException) {
            e.printStackTrace()
        } finally {
            process?.destroy()
        }
        return false
}

Android 代码执行ADB命令

private fun execute(command: String) {
    var process: Process? = null
    lateinit var bufferedReader: BufferedReader
    lateinit var errorBufferedReader: BufferedReader
    try {
        process = Runtime.getRuntime().exec(command)
        bufferedReader = BufferedReader(InputStreamReader(process.inputStream))
        errorBufferedReader = BufferedReader(InputStreamReader(process.errorStream))
        val result = StringBuffer()
        val error = StringBuffer()
        while (true) {
            val readLine = bufferedReader.readLine()
            if (readLine != null) {
                result.append(readLine)
            } else {
                break
            }
        }
        while (true) {
            val readLine = errorBufferedReader.readLine()
            if (readLine != null) {
                error.append(readLine)
            } else {
                break
            }
        }
        println("shuxin.wei exec: $command")
        println("shuxin.wei result:${process.exitValue()}  $result")
        println("shuxin.wei error: $error")
        process.waitFor()
    } catch (e: IOException) {
        e.printStackTrace()
    } finally {
        bufferedReader.close()
        errorBufferedReader.close()
        process?.destroy()
    }
}
