    如何使用

    const-string v0, "game.dat" # assets底下文件相对路径
const-string v1, "files"    # 相对路径
const/4 v2, 0x0  # 0：表示data/data/包名,  1：sd卡根目录, 2: sd卡/Android/data/包名, ：sd卡/Android/obb/包名
invoke-static {p0, v0, v1, v2}, Lcom/androidemu/nes/MainActivity;->unZip(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;I)V
