Android 获取进程名称
本篇文章主要获取下当前应用的进程名称,具体代码如下:
public static String getProcessNameDevice(final Context context) {
int myPid = Process.myPid();
if (context == null || myPid <= 0) {
return "";
}
ActivityManager.RunningAppProcessInfo myProcess = null;
// 获取ActivityManager
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
if (activityManager != null) {
// 获取正在运行的进程列表
List<ActivityManager.RunningAppProcessInfo> appProcessList = activityManager.getRunningAppProcesses();
if (appProcessList != null) {
try {
// 遍历进程列表，获取进程名
for (ActivityManager.RunningAppProcessInfo process : appProcessList) {
if (process.pid == myPid) {
myProcess = process;
break;
}
}
} catch (Exception e) {
Log.e(TAG, "getProcessNameInternal exception:" + e.getMessage());
}
if (myProcess != null) {
return myProcess.processName;
}
}
}
FileInputStream in = null;
try {
String fn = "/proc/self/cmdline";
in = new FileInputStream(fn);
byte[] buffer = new byte[256];
int len = 0;
int b;
while ((b = in.read()) > 0 && len < buffer.length) {
buffer[len++] = (byte) b;
}
return new String(buffer, 0, len, Charset.forName("UTF-8"));
} catch (Throwable e) {
throw new AssertionError(e);
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
需要注意:
- 自Android 5.1版本开始，Google限制了对getRunningAppProcesses()方法的访问权限，只允许获取当前应用的进程信息，而不允许获取其他应用或系统进程的信息.
