异常的Drawable.createFromResourceStream（） - HTC而已？ [英] Exception in Drawable.createFromResourceStream() -- HTC ONLY?

问题描述

我已经发布了输入法（软键盘）的应用程序，我正在崩溃报告从 HTC手机仅。这里是堆栈跟踪：

I've released an IME (soft keyboard) app and I am getting crash reports from HTC phones only. Here is the stack trace:

java.lang.NullPointerException
    at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:465)
    at android.graphics.drawable.Drawable.createFromResourceStream(Drawable.java:697)
    at android.graphics.drawable.Drawable.createFromResourceStream(Drawable.java:666)
    at com.comet.android.keyboard.util.Util.getBitmapDrawable(MyFile.java:416)
    ...

这是我的呼吁Drawable.createFromResourceStream（）

Here is my call to Drawable.createFromResourceStream()

drawable = Drawable.createFromResourceStream(context.getResources(), null, stream, null);

其中，上下文的 InputMethodService 和流的一个子类要么是的FileInputStream 或 AssetInputStream 的（我都试过）。资源文件编译的 NinePatchDrawable 的。我已经证实该流不为空。

where context a subclass of InputMethodService and stream either is a FileInputStream or AssetInputStream (I've tried both). The resource file is a compiled NinePatchDrawable. I've confirmed that stream is not null.

要重复：这个错误只发生在特定的HTC手机（包括埃沃）运行各种版本的Andr​​oid操作系统的

To repeat: this bug only happens with certain HTC handsets (including the Evo) running various versions of Android OS.

有没有人经历过这种和/或不知道如何解决它？

Has anyone experienced this and/or know how to fix it?

在此先感谢，

巴里

P.S。奇怪的是崩溃线465不在大跌方法的 BitmapFactory.de codeResourceStream（）的任何版本的 BitmapFactory.java 的那么HTC必须使用修改$ C $℃。

P.S. What is strange is that crash line 465 is not within crash method BitmapFactory.decodeResourceStream() in any version of BitmapFactory.java so HTC must be using modified code.

推荐答案

找到了一个解决这个问题，你可以用替换调用 Drawable.createFromResourceStream ：

Found a solution for this problem, you can replace the call to Drawable.createFromResourceStream with:

// set options to resize the image
Options opts = new BitmapFactory.Options();
opts.inDensity = 160;

Drawable drawable  = null;
Bitmap bm = BitmapFactory.decodeFile(file.getAbsolutePath(), opts);
if (bm != null) {
  drawable = new BitmapDrawable(context.getResources(), bm);
}

这仅适用于文件。
