Dumpsys许可拒绝在java中

问题描述

我想获得dumpsys统计[喜欢dumpsys cpuinfo中，dumpsys电池。我在java中执行这些并将其写入文件。但我得到，

  2012.06.20 7时32分19秒
权限拒绝：不能私自从PID = 862，UID = 10040倾倒cpuinfo的android.permission.DUMP
所有dumpsys命令。
 

我已经加入和android.permission.BATTERY_STATS的权限android.permission.DUMP android.manifest。但是，没有获得resulyPlease帮助其critical.The code我用的是如下其中cmd包含dumpsys cpuinfo的或dumpsys电池[人]

 日历CAL = Calendar.getInstance（）;
SimpleDateFormat的SDF =新的SimpleDateFormat（YYYY.MM.DD HH：MM：SS）;
System.setOut（新的PrintStream（新的FileOutputStream（/ SD卡/显示器/+文件+TXT，FALSE）））;
的System.out.println（\ñ\ N+ sdf.format（cal.getTime（）））;
Log.w（CMD-FN，CMD）;
。工艺=调用Runtime.getRuntime（）EXEC（CMD）;
process.waitFor（）;
BufferedReader中的BufferedReader =新的BufferedReader（新的InputStreamReader（process.getInputStream（）））;
字符串缓冲区=;

而（（缓冲= bufferedReader.readLine（））！= NULL）
      {
    //fileobj.write(buffer）;
    的System.out.println（缓冲液）;
    //output.write(buffer）;
}
    缓冲=;
    的BufferedReader缓冲=新的BufferedReader（新的InputStreamReader（process.getErrorStream（）））;
    而（（缓冲= buffered.readLine（））！= NULL）
        {
        Log.w（异常，缓冲区）;
        }
 

下面是我的清单项目

 ＆LT;使用-权限的Andr​​oid：名称=android.permission.WRITE_EXTERNAL_STORAG​​E/＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.INTERNET对/＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.DUMP/＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.BATTERY_STATS/＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.READ_PHONE_STATE/＆GT;
 

解决方案

转储权限被定义为安卓的ProtectionLevel =signatureOrSystem所以你不能把它除非您的应用程序与平台密钥签名，或安装在系统分区。

I am trying to obtain the dumpsys statistics [like dumpsys cpuinfo, dumpsys battery]. I executing these in java and writing it to a file. But I am getting,

2012.06.20 07:32:19
Permission Denial: can't dump cpuinfo from from pid=862, uid=10040 without permission android.permission.DUMP
for all dumpsys commands.

I have added the permission "android.permission.DUMP" and "android.permission.BATTERY_STATS" in android.manifest. But, not obtaining the resulyPlease help as its critical.The code I use is as below where cmd contains dumpsys cpuinfo or dumpsys battery [anyone]

Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
System.setOut(new PrintStream(new FileOutputStream("/sdcard/Monitor/"+file+".txt",false)));
System.out.println("\n\n"+sdf.format(cal.getTime()));           
Log.w("cmd-fn", cmd);
process=Runtime.getRuntime().exec(cmd);
process.waitFor();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String buffer="";

while((buffer=bufferedReader.readLine())!=null)
      {
    //fileobj.write(buffer);
    System.out.println(buffer);
    //output.write(buffer);
}
    buffer="";
    BufferedReader buffered = new BufferedReader(new InputStreamReader(process.getErrorStream()));
    while((buffer=buffered.readLine())!=null)
        {
        Log.w("exception",buffer);
        }

Below is my manifest entries

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.DUMP" />
<uses-permission android:name="android.permission.BATTERY_STATS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

解决方案

The DUMP permission is defined as android:protectionLevel="signatureOrSystem" so you can't get it unless your app is signed with the platform key, or installed in the system partition.
