这几天我一直在想办法，但无济于事。我正在使用 Titanium 开发一个简单的 android 应用程序，它在 iOS 上运行良好。然而，当我在 android 上启动它时，它永远不会启动。这是我的 manifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.tiki.signals" android:versionCode="1"

    />

</manifest>

这是日志猫：

这里发生了什么？我在 logcat 中没有看到任何错误。虚拟机只是无缘无故地关闭。请帮忙！

仅查看 logcat 就会想到一个项目...内存不足。你会看到免费内存下降到 3% YIKES!。通常尽量保持 10% 的空闲，否则操作系统可能会进入分页状态，并且可能会使某些功能超时。

禁用应用程序中的某些功能并观察模拟器下的内存。最好的建议是将应用程序安装到实际手机上，尽管模拟器应该提供接近真实世界的结果。我不指望很好地模拟任何硬件设备。

这是一些转储内存使用情况的代码。你需要找出你的目标类是什么。在操作系统开始选择您的应用程序之前，较旧的手机只有 16MB，较新的手机只有 48MB。将代码放入 Oncreate。

 Runtime rt = Runtime.getRuntime();
 long maxMemory = rt.maxMemory();
 Log.v("onCreate", "maxMemory:>>>>>" + Long.toString(maxMemory));   //max available memory to use

 ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
 int memoryClass = am.getMemoryClass();
 Log.v("onCreate", "memoryClass:>>>>" + Integer.toString(memoryClass));  //max available you should use to keep from getting bumped off

 printl("PGM MEM FREE MB", GetInternalMemAvail());
 printl("INTERNAL STORAGE FREE MEMORY BYTES",getmem());
 printl("INTERNAL TOTAL MEMORY BYTES",TotalMemory());
 printl("SD MEM FREE MB",GetSDMemAvail());
 printl("SD MEM GB",getAvailableSpaceInGB());

 private static void printl(String printstring,long x)
 {
  String temp;
  temp=String.format(" %d",x);
  Log.e(printstring,temp);  
 }
