Android 获取assets绝对路径

搜索了很久，发现普通方式获取不到assets的绝对路径。于是换个思路。。

因为assets绝对路径未知，但是SD卡根目录等目录是已知的。于是可以先将文件转移到已知的目录中，再行操作。

代码如下：

AssetManager am = this.getAssets();InputStream is = am.open("xxx.apk");// 获取SD卡根路径String sdPath = Environment.getExternalStorageDirectory().getPath();FileOutputStream fos = new FileOutputStream(sdPath + "/xxx.apk");// 写入SD卡byte[] buff = new byte[512];int count = is.read(buff);while (count != -1){fos.write(buff);count = is.read(buff);}is.close();fos.close();
