如何运行Android APK包中的控制台程序？

Question

APK 是用 RAD Studio C++Builder 11.2 编写的。

比如我试了很多方法都编译出错

代码如下：

UnicodeString command = "test_run"; 
TFileName fullPath = TPath::Combine(TPath::GetDocumentsPath(), command);

TProcess* process = new TProcess(NULL);
process->Executable = fullPath;

TStreamReader* output = new TStreamReader(process->Output);
process->Execute();
Memo1->Lines->Add(output->ReadLine());
output->Free();
process->Free();

TProcess

在 RAD Studio 11.2 中不存在

另一种方式：

#define TArray System::TArray__1
#define TJavaArray TJavaArray__1
#define JString Androidapi::Jni::Javatypes::_di_JString

JString jCommand = StringToJString("test_run");  
JString jOutput = StringToJString(""); 
TArray<System::Byte> *jResult = NULL; 

try {
    _di_JRuntime rt = TJRuntime::JavaClass->getRuntime();
    _di_JProcess proc = rt->exec(jCommand);  
    _di_JInputStream is = proc->getInputStream(); 
    TJavaArray<System::Byte> *jdata = new TJavaArray<System::Byte>(1024);
    while (is->available() > 0) {
        int count = is->read(jdata,0,jdata->Length);
        jOutput = jOutput + JStringToString(TJString::JavaClass->init(jdata,count));
    }
    jResult = new TArray<System::Byte>(jdata);
} catch (...) {
    ShowMessage("Error: cannot run command");
    jOutput = "";
}

卡在

JRuntime

.

我不知道如何使用 FMX 框架运行控制台命令。

有人能帮忙吗？
