判断一个应用是否在运行，卸载应用，从一个应用启动另一个应用
1、判断集团无线城市客户端是否在启动
ActivityManager am = (ActivityManager)VersionUpdateActivity.this.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningTaskInfo> list = am.getRunningTasks(100);
for (RunningTaskInfo info : list)
{
if (info.topActivity.getPackageName().equals("com.whty.wicity.china")
&& info.baseActivity.getPackageName().equals("com.whty.wicity.china"))
{
LogManager.showLog(TAG, "==============集团无线城市客户端已经启动=====================", LogManager.DEBUG);
isAppRunning = true;
break;
}
}
2、卸载无线城市客户端
Uri uri = Uri.parse("package:" + "com.jscity");
Intent intent = new Intent(Intent.ACTION_DELETE, uri);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
3、判断一个应用是否存在
PackageInfo packageInfo;
String packagename = "com.whty.wicity.china";
try
{
packageInfo = mContext.getPackageManager().getPackageInfo(packagename, 0);
}
catch (NameNotFoundException e)
{
packageInfo = null;
e.printStackTrace();
}
if (null == packageInfo)
{
return false;
}
else
{
return true;
}
通过一个apk去启动另一个apk
Intent mIntent = new Intent();
ComponentName comp =
new ComponentName("com.whty.wicity.china", "com.whty.wicity.china.home.WicityHomeActivity");
mIntent.setComponent(comp);
mIntent.setAction("android.intent.action.VIEW");
startActivity(mIntent);
this.finish();
