SDL for Android: compile but don't work

SDL Development
1

Hello there

I work with MacOSX (10.6), and want to use SDL on my Android phone (v1.6).
I use NDK and ndk-build to build the binary.
I downloaded the demo project android-project.zip
I can easily compile and send the program to the emulator or the device,
but it just launch and exit immediatly.

Here is the adb logcat:

I/ActivityManager( 68): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=org.libsdl.app/.SDLActivity }

I didn’t edited anything in the original source code, just did “ndk-build”, and then imported using Eclipse like explained in README.android:

?Once you’ve copied the SDL android project and customized it, you can create an Eclipse project from it:

  • File -> New -> Other
  • Select the Android -> Android Project wizard and click Next
  • Enter the name you’d like your project to have
  • Select “Create project from existing source” and browse for your project directory
  • Make sure the Build Target is set to Android 1.6
  • Click Finish?

I can’t understand, can you help me please? (Emulator is default android 1.6)

Thank you all

I just updated the Eclipse plugins, the Android tools, the API SDKs, NDK to
r5b, removed all my old virtual machines and created a new Android 2.1
virtual machine with 64 MB SDcard and otherwise default settings.

The I updated the demo project with the latest SDL and ran the following
steps while the new emulator was running:
ndk-build
ant install
sh data.sh <-- important!

I then ran the SDL application on the emulator and blasted some aliens. :slight_smile:

Here’s the demo project with the latest SDL:

See ya!On Mon, Mar 14, 2011 at 1:35 AM, Globoeil wrote:

just working on trying to finish a pure android game right now!

is this SDL only going to run 2.2 above?

It actually supports 1.6 and above, but the OpenGL ES 2 renderer requires
2.1.On Tue, Mar 15, 2011 at 11:56 PM, Neil White wrote:

Hi,

Note that r5b apparently hangs on pre 2.2 phones. r4b is the one I’ve seen
used with the other SDL port. But they are fairly different sdks.
