Android中通过pid获取app包名
example :
if(packageNames.length >1){
int pid = Binder.getCallingPid();
int uid = Binder.getCallingUid();
ActivityManager am = (ActivityManager)mContext.getSystemService(mContext.ACTIVITY_SERVICE);
List runningApps = am.getRunningAppProcesses();
if (runningApps != null && runningApps.size() > 0) {
for (ActivityManager.RunningAppProcessInfo app : runningApps) {
if(app.pid == pid && app.uid ==uid){
packageNames[0] = app.processName;
break;
}
}
}
}
网络上的案例：
String callerPackage = getAppNameByPID(getContext(), Binder.getCallingPid());
private String getAppName(int pID){ String processName = ""; ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE); List l = am.getRunningAppProcesses(); Iterator i = l.iterator(); PackageManager pm = this.getPackageManager(); while(i.hasNext()) { ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next()); try { if(info.pid == pID) { CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA)); //Log.d("Process", "Id: "+ info.pid +" ProcessName: "+ info.processName +" Label: "+c.toString()); //processName = c.toString(); processName = info.processName; } } catch(Exception e) { //Log.d("Process", "Error>> :"+ e.toString()); } } return processName;}
ActivityManagerService.java
@Override
public List getRunningExternalApplications() {
enforceNotIsolatedCaller("getRunningExternalApplications");
List runningApps = getRunningAppProcesses();
List retList = new ArrayList();
if (runningApps != null && runningApps.size() > 0) {
Set
for (ActivityManager.RunningAppProcessInfo app : runningApps) {
if (app.pkgList != null) {
for (String pkg : app.pkgList) {
extList.add(pkg);
}
}
}
}
