From 6e01fbb7632a212a213c361d103f7039f90107bb Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Sun, 11 Feb 2018 18:23:37 -0800 Subject: [PATCH] On Android show the system UI when an SDL window is windowed, hide the system UI when it's fullscreen, like we do on iOS. We're increasing the Android SDK minimum version to API 19, this doesn't increase the minimum target API, which is API 14. --- android-project/app/build.gradle | 6 +-- android-project/app/jni/Application.mk | 2 +- .../main/java/org/libsdl/app/SDLActivity.java | 49 +++++++++++++------ docs/README-android.md | 2 +- src/core/android/SDL_android.c | 11 ++++- src/core/android/SDL_android.h | 1 + src/video/android/SDL_androidvideo.c | 16 +++--- src/video/android/SDL_androidwindow.c | 7 ++- src/video/android/SDL_androidwindow.h | 1 + 9 files changed, 66 insertions(+), 29 deletions(-) diff --git a/android-project/app/build.gradle b/android-project/app/build.gradle index 3fe554067..2475c1714 100644 --- a/android-project/app/build.gradle +++ b/android-project/app/build.gradle @@ -8,14 +8,14 @@ else { } android { - compileSdkVersion 16 + compileSdkVersion 19 buildToolsVersion "26.0.1" defaultConfig { if (buildAsApplication) { applicationId "org.libsdl.app" } minSdkVersion 14 - targetSdkVersion 16 + targetSdkVersion 19 versionCode 1 versionName "1.0" externalNativeBuild { @@ -65,4 +65,4 @@ dependencies { exclude group: 'com.android.support', module: 'support-annotations' }) testCompile 'junit:junit:4.12' -} \ No newline at end of file +} diff --git a/android-project/app/jni/Application.mk b/android-project/app/jni/Application.mk index e84be0235..246136dc6 100644 --- a/android-project/app/jni/Application.mk +++ b/android-project/app/jni/Application.mk @@ -5,5 +5,5 @@ APP_ABI := armeabi-v7a arm64-v8a x86 x86_64 -# Min SDK level +# Min runtime API level APP_PLATFORM=android-14 diff --git a/android-project/app/src/main/java/org/libsdl/app/SDLActivity.java b/android-project/app/src/main/java/org/libsdl/app/SDLActivity.java index 3768310d7..750db69fa 100644 --- a/android-project/app/src/main/java/org/libsdl/app/SDLActivity.java +++ b/android-project/app/src/main/java/org/libsdl/app/SDLActivity.java @@ -213,19 +213,7 @@ public class SDLActivity extends Activity { setContentView(mLayout); - /* - * Per SDL_androidwindow.c, Android will only ever have one window, and that window - * is always flagged SDL_WINDOW_FULLSCREEN.
