You could try

问题 I'm not new to Android and I'm well used to the version handling and how to condition it, but when I see this it troubles me... // Check if we're running on Android 5.0 or higher if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // Call some material design APIs here } else { // Implement this feature without material design } On any device pre lollipop this line would crash the app because the Build.VERSION_CODES.LOLLIPOP field does not exists... so why is this in the recommended

问题 is it possible to show widget in "Add to home screen > Widgets" Dialog only for a certain android version without uploading two APKs and assigning to proper SDK version numbers? 回答1: I have a way to do it without any code e.g.: In your res\values dir create a bools.xml file: <?xml version="1.0" encoding="utf-8"?> <resources> <bool name="honeycombOrAbove">false</bool> </resources> Create a values-v11 dir (for honeycomb or above values), copy the file to it and set the value to true.

问题 I know there are a lot of questions on here about Android API Level and Version but this question is different so please don't mark it as a duplicate. I am wondering how Java version 1.6, 1.7, 1.8... relates to those two. The source of my confusion is me trying to use the Pattern.compile method with the Pattern.UNICODE_CHARACTER_CLASS flag as seen below. Pattern pattern = Pattern.compile("\\b" + keywordToCheck + "\\b", Pattern.UNICODE_CHARACTER_CLASS); From the docs on Pattern.UNICODE

问题 When I've applied ripple effect to the UI having OS version lower than lollipop, at that time first of all, ripple effect is completed and then other UI process is started. So, it is making UI process slower: as ripple animation is completing first of all and then doing next UI process. 回答1: As per my understanding...You are asking that Why ripple effect is smooth on devices having lollipop or later versions while not working so smooth on devices having older versions then lollipop? If so

问题 in my app i have two set of designs. One design is for the android devices version of 2.1 and 2.2, the other design is for devices of 2.3 and above.

When i run this build in 2.3.4 devices it gets run properly. How does it happens? I am planning to submit the app with multiple apk files in

问题 In the past I used the following configuration in my gradle file for version code generation using apk splitting: splits { abi { enable true reset() include 'x86', 'armeabi', 'armeabi-v7a', 'arm64-v8a' universalApk true } } project.ext.versionCodes = ['armeabi': 1, 'armeabi-v7a': 2, 'arm64-v8a': 3, 'mips': 5, 'mips64' : 6, 'x86': 8, 'x86_64': 9] android.applicationVariants.all { variant -> variant.outputs.each { output -> output.versionCodeOverride = project.ext.versionCodes.get(output

问题 I have seen many examples in different android libraries about detecting if device is LOLLIPOP supported or not. But when I use it in my app, it is throwing the following error: Error:(20, 60) error: cannot find symbol variable LOLLIPOP For example my source code is: static boolean isLollipop() { return Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP || Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP_MR1; } I am using the latest version of Android Studio with all packages updated

问题 I have this very unpeculiar exception.The thing is have i have this app that has a button to start InputMethodService that starts like this public class MyGroovyIme extends InputMethodService { and this is how it looks in manifest. <service android:name=".MyGroovyIme" android:enabled="true" android:exported="true" android:permission="android.permission.BIND_INPUT_METHOD" > <intent-filter> <action android:name="android.view.InputMethod" /> <!-- <category android:name="android.intent.category

问题 I am creating multiple apk's for each ABI , I did this to assign separate version code to each apk. ext.abiCodes = ['armeabi-v7a':1, mips:2, x86:3] import com.android.build.OutputFile android.applicationVariants.all { variant -> variant.outputs.each { output -> def baseAbiVersionCode = project.ext.abiCodes.get(output.getFilter(OutputFile.ABI)) if (baseAbiVersionCode != null) { output.versionCodeOverride = baseAbiVersionCode * 1000 + variant.versionCode } } } This is my dafaultConfig , and the
