如何包装AndroidNDK的样本？

Question

这是一个普通的问题，但我在stackoverflow中找不到任何类似的问题来讨论Android SDK/NDK最近版本的解决方案。

我的目的是将Android NDK打包为apk文件。

所以：

1. 我将Android NDK安装到 /opt目录-称为 /opt/.
2. 和cd /opt//样本/哪里是任何示例。
3. 然后输入/opt//ndk-build，就编译好了：

/opt/android-ndk/ndk-build

如何克服上述编译错误？

谢谢

Answer 1

首先，看起来你构建了hello-jni的本机端，然后构建并打包了hello-gl2。这是两个不同的示例。你能确保你保持在同一个示例文件夹中吗？

我还强烈建议您将/opt/android-ndk-r10e、/opt/android-sdk-linux/tools和/opt/android-sdk-linux/Platform-tools添加到您的PATH环境变量。只需将此行添加到您的~/. profile，然后重新启动您的终端。

export PATH=${PATH}:/opt/android-ndk-r10e;/opt/android-sdk-linux/tools:/opt/android-sdk-linux/platform-tools"

通过这种方式，您应该能够访问任何android工具，如ndk build、adb和android，而无需指定它们的绝对路径。

如果这没有帮助，请尝试用蚂蚁清洁来清理和重建样品

< li >斌/ < li>gen/ < li>libs/ < li>obj/ < li>build.xml < li>local.properties < li>proguard-project.xml

然后重试：

ndk-build NDK_DEBUG=1
android update project --path . --target android-21
ant debug

一切都应该正常。如果它仍然不起作用，我建议启动android（无参数）以启动Android SDK管理器。确保您是最新的，并确保您安装了适用于API级别21的SDK Platform，如果这是您要使用的API级别。截至今天的最新Android SDK工具应该是版本24.2。确保您也拥有最新的android-ndk。截至今天的最新版本应该是r10e。

祝你好运
