sdk

问题 I need that if the tablet does not have the menu hardware button... it will show the menu button on the software buttons as you see here: So I've googled a bit and found out that to display this button you only need to: "set minSdkVersion to 10 or lower, set targetSdkVersion to 11, 12, or 13, and you do not use ActionBar, the system will add the legacy overflow button when running your app on a handset with Android 4.0 or higher."

问题 I've released an android app with the property <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/> now my app seems to crash on android 1.5 devices (i guess because i use drawable-mdpi/hdpi,...) so thought it would be good to release the same app just for 1.5 devices (not using the mdpi/hdpi-directories). but when i use <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="3" android:maxSdkVersion="3" /> it doesn't compile for 1.5 (it states that target and

问题 if i use android 4.1.2 (API 16) Android SDK will my apps work on Android 2.3 phones. i have downloaded android 4.1.2 sdk tools and other packages. 回答1: You will need to set the minimum SDK attribute in your manifest to 2.3 to ensure you app will work on earlier versions of the OS. Your app will work fine, assuming you are not using any API calls from a later version. The Android Dev team suggests you always compile against the newest version you can support. So, you are on the right track. So

问题 I only have a switch toggle on my fragment. What is the app doing now: The user opens the app and selects "Laptop" over the navigation drawer and then he sees a switch (it is a "slider" which you can move to on or off...hope you understand what I mean).
