修改smali文件，重打包，实现调用第三方SO文件

Java代码：

static{
        // //loadlibary里 要把SO文件名的lib和后缀去掉。libfgma.so --> fgma
        System.loadLibrary("fgma");
    }

对应Smali：

# direct methods
.method static constructor <clinit>()V
    .locals 

    .prologue
    .line
    const-string v0, "fgma"
    invoke-static {v0}, Ljava/lang/System;->loadLibrary(Ljava/lang/String;)V

    .line
    return-void
.end method

对so中函数的声明：

public native String GetLocalPort();

对应Smali：

# virtual methods
.method public native GetLocalPort()Ljava/lang/String;
.end method

调用：

String str = GetLocalPort();
Toast.makeText(this, str, Toast.LENGTH_LONG).show();    

对应Smali：

.line
 invoke-virtual {p0}, Lcom/dit/mobile/android/fgma3/Mary;->GetLocalPort()Ljava/lang/String;
 move-result-object v0

 .line
 .local v0, "str":Ljava/lang/String;
 const/ v1, 0x1

 invoke-static {p0, v0, v1}, Landroid/widget/Toast;->makeText(Landroid/content/Context;Ljava/lang/CharSequence;I)Landroid/widget/Toast;
 move-result-object v1
 invoke-virtual {v1}, Landroid/widget/Toast;->show()V
