androidstudio需要安装jdk吗_android studio怎么配置jdk

我需要javah和android-ndk的帮助。JAVAH找不到类(android ndk)

我tryed生成H-文件我的本地方法，但JAVAH说类文件未找到。

我的目标类有绝对的名称$ PROJECT_DIRECTORY/的src/BT/nativeclient/BtnativeActivity.java，包含跟随代码：

package bt.nativeclient;

import android.app.Activity; import android.os.Bundle; import android.widget.TextView;

public class BtnativeActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

TextView tv = new TextView(this);

tv.setText(stringFromJNI());

setContentView(tv);

}

public native String stringFromJNI();

static

{

System.loadLibrary(“hello-jni”);

}

}

我tryed开始JAVAH从如下pathes：

$(PROJECT_DIRECTORY)/bin$ javah -jni bt.nativeclient.BtnativeActivity

$(PROJECT_DIRECTORY)/jni$ javah -jni bt.nativeclient.BtnativeActivity

$(PROJECT_DIRECTORY)$ javah -jni bt.nativeclient.BtnativeActivity

我试着指定-classpath修改：

$PROJECT_DIRECTORY/src$ javah -classpath :. bt.nativeclient.BtnativeActivity

我tryed指定的android.jar提到​​：

$PROJECT_DIRECTORY/bin$ javah -classpath :/home/l/android-sdks/platforms/android-10/android.jar:. bt.nativeclient.BtnativeActivity

但我总是得到结果只有一个：

error: cannot access bt.nativeclient.BtnativeActivity

class file for bt.nativeclient.BtnativeActivity not found

javadoc: error – Class bt.nativeclient.BtnativeActivity not found.

Error: No classes were specified on the command line. Try -help.

而且，随着-verbose选项命令javah说，这个命令是seaching我的类它有效的地方：

$PROJECT_DIRECTORY/src$ javah **-verbose** -classpath :/home/l/android-sdks/platforms/android-10/android.jar:. bt.nativeclient.BtnativeActivity

error: cannot access bt.nativeclient.BtnativeActivity

class file for bt.nativeclient.BtnativeActivity not found

javadoc: error – Class bt.nativeclient.BtnativeActivity not found.

Error: No classes were specified on the command line. Try -help.

我觉得我失去了一些重要的东西，但我仍然无法找到解决方案。

请问有人可以帮我吗？
