问题 I need to launch an activity (not the main activity) of an application from an application I have made. The activity I want to launch is proprietary, hence, I cannot make any changes to its code(or manifest). For example: I want to launch somebody's Facebook profile from my own application. A normal intent to facebook from my app would open the 'newsfeed'(which I don't want). I want to know how to access any other activity. Thanks in advance! The little code I have: String PACKAGE="com

问题 I want to list all the intent filters that are present in an package. I am trying to do it using PackageManager class.

EDIT: As per the advice given below I ended up implementing it like this: Intent i = new Intent(Intent.ACTION_CALL); i.setData(Uri.parse("tel:123456789")); ResolveInfo

问题 If I use the code below to disable a static BroadcastReceiver defined in AndroidManifest.xml, will it be re-enabled after a reboot? It doesn't appear to be but the docs don't say whether it should. final ComponentName compName = new ComponentName(context, MyBroadcastReceiver.class); context.getPackageManager().setComponentEnabledSetting( compName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); Thanks in advance... 回答1: Is PackageManager

问题 If I call PackageManager pm = getPackageManager () ; List<PackageInfo> pis = pm.getInstalledPackages (PackageManager.GET_PROVIDERS) ; I get a list of installed packages, including any provivders they declare (i.e, with pis[i].providers possibly being non-null). However, if I include PackageManager.GET_ACITIVITIES among the flags, as in PackageManager pm = getPackageManager () ; List<PackageInfo> pis = pm.getInstalledPackages (PackageManager.GET_ACTIVITIES | PackageManager.GET_PROVIDERS) ; I

问题 I am trying to implement this great technique of sharing preferences across two different applications while still MODE_PRIVATE. My problem is that the first application cannot assume that the first application is installed (and vice versa) and so: Context c = createPackageContext("com.app.first", MODE_PRIVATE); Must be replaced by: Context c = createPackageContext("com.app.shared", MODE_PRIVATE); But that mandates adding that com.app.shared for real, which translates into a second APK? In
