问题 I've set intent filter label as per and per and per official docs: The icon and label that are set in a component's are shown to the user whenever that component is presented as an option to fulfill an intent. By default, this icon is inherited from whichever icon is declared for the parent component (either the or element), but you might want to change the icon for an intent filter if it provides a unique action that you'd like to better indicate in the chooser dialog. For more information,

问题 Good morning, i am quite new in Android and i have a problem setting the color of the built-in action bar in Google Places Picker. The documentation of this one clearly says that the action bar color inherits the matherial theme style of the project.

I would like to ask if it's somehow possible to replace Theme

问题 Code such as : if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) ed.apply(); else ed.commit(); produces a warning in Froyo : 04-27 03:40:35.025: W/dalvikvm(3138): VFY: unable to resolve interface method 219: Landroid/content/SharedPreferences$Editor;.apply ()V But I understand that in older devices this would be a RuntimeError which would abort the application (see here and here). So is this way of conditionally calling new API (methods) safe in API 8 (Froyo) and above

问题 I've got an app that uses the accessibility service to monitor for events. It's always worked fine in versions of android up to ICS, but with Jelly bean I'm not having much luck. As the documents mention I've added android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" to my service in the manifest file. This causes the app to work fine using the declarative xml method for the xml. The problem is on backwards compatibility. For versions such as gingerbread I'm now getting the

问题 I am using 'com.google.android.gms:play-services-ads:12.0.1'. and android support version 27.1.1. when I try to upgrade my ads library to the latest (15.0.0) I get an error saying that I must use the same version specification.

问题 I'm trying to use Fragments and ActionBar in a Android 2.2 project. There is some error when using "?android:attr/actionBarSize", how to get and set that value correctly?

问题 So I'm getting really frustrated with android and the fact half the stuff doesn't work when you roll back the API Level past 11. Why isn't it easy and well done like iOS?! The Problem I am using ObjectAnimators to animate the transitioning between Fragments . They work fine in anything with API Level 11 and above. As soon as I change the build target to less than 11 I get problems with it saying it can't found the resource identifiers for attributes such as propertyName and valueType in the
