问题描述
我想编写一个应用程序读取所有的日志我的设备上。我有一个客户/服务架构,我看到从客户端和服务流程的日志消息,但我没有看到在手机上的任何其他应用程序的任何消息(我不看其他的信息使用桌面logcat中)。
我是否需要root?
code片段
清单
<使用-权限的Android:名称=android.permission.READ_LOGS/>
日志读取器
调用Runtime.getRuntime()EXEC(logcat的-c)WAITFOR()。
。工艺过程=调用Runtime.getRuntime()EXEC(logcat的-v长*:*);
BufferedReader中读取=
新的BufferedReader(新的InputStreamReader(process.getInputStream()));
而(真){
串nextLine = reader.readLine();
如果(!nextLine.contains(LogWatcher-D)){
Log.w(LogWatcher-D,见:+ nextLine);
}
//处理线
}
在Android 4.1及更高版本,可以通过记录你的进程只能访问日志信息,除非你持有 READ_LOGS
许可。该权限要求要么您的应用程序所签署设备的固件,或者你的应用程序安装在系统分区上的相同签名密钥进行签名。
I'm trying to write an app that reads all logs on my device. I've got a client/service architecture, and I see log messages from both the client and service processes but I don't see any messages from any other applications on the phone (I do see other messages using the desktop logcat).
Do I need root?
Code Snippets
Manifest
<uses-permission android:name="android.permission.READ_LOGS" />
Log Reader
Runtime.getRuntime().exec("logcat -c").waitFor();
Process process = Runtime.getRuntime().exec("logcat -v long *:*");
BufferedReader reader =
new BufferedReader(new InputStreamReader(process.getInputStream()));
while (true) {
String nextLine = reader.readLine();
if (!nextLine.contains("LogWatcher-D")) {
Log.w("LogWatcher-D", "See: " + nextLine);
}
// Process line
}
On Android 4.1+, you can only access log messages logged by your process, unless you hold the READ_LOGS
permission. That permission requires either that your app be signed by the same signing key that signed the device's firmware, or that your app is installed on the system partition.
