小编Nat*_*obs的帖子

我做一个Android应用程序,用于HttpUrlConnection,POST方法, HoloEverywhere库但我有问题...为什么会发生我不知道的问题...我认为getOutputStream()错误,因为如果用于getOutputStream()方法显示消息"应用程序不幸,*已停止." 并停止申请.

main.java

import java.io.BufferedOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;

import com.actionbarsherlock.app.SherlockActivity;

public class Main extends SherlockActivity {
    EditText ID, PS;
    String myId, myPs, myResult;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        findViewById(R.id.login_button).setOnClickListener(mClickListener);
    }

    Button.OnClickListener mClickListener = new Button.OnClickListener() {
        public void onClick(View v) {
            ID = (EditText)findViewById(R.id.id_text);
            PS = (EditText)findViewById(R.id.ps_text);
            myId …

我想清除使用printf语句生成的C程序的输出.我想只清除一行,例如:

[资源]

printf("AAAAAAAAAAAAAA\n");
printf("BBBBBBBBBBBBBB\n");
printf("CCCCCCCCCCCCCC\n");
printf("DDDDDDDDDDDDDD\n");

[终奌站]

AAAAAAAAAAAAAA
BBBBBBBBBBBBBB
CCCCCCCCCCCCCC
DDDDDDDDDDDDDD

[我希望]

AAAAAAAAAAAAAA
BBBBBBBBBBBBBB
CCCCCCCCCCCCCC

我将"DDDDDDDDDDDDDD"行写入其他字符串.我只想要留下上面的A,B,C语句.只有明确的D句改变其他句子,无条件输出D句.

我该怎么做呢？

我有一些问题.

我使用ndk-build但我不能创建库*.so.

---------------------------------错误---------------- -----------------

nathaniel@Nathaniel-MSI /work/workspace/HealthCare $ ndk-build
 make: *** No rule to make target `jni/jni/src/filterData.c', needed by
 `obj/local/armeabi/objs/HealthCare/jni/src/filterData.o'.  Stop.

根据我的Android.mk来源,请帮帮我

--------------------------------- Android.mk -------------- -------------------

LOCAL_PATH          := $(call my-dir)
SRCS                := $(wildcard $(LOCAL_PATH)/src/*.c)

include $(CLEAR_VARS)

LOCAL_MODULE        := HealthCare
LOCAL_SRC_FILES     := $(SRCS)

LOCAL_LDLIBS        := -llog

include $(BUILD_SHARED_LIBRARY)

我的LogCat出现了一些错误......

E/Trace(627): error opening trace file: No such file or directory (2)

然后我找不到解决方案请帮助我.PS.我正在尝试将我的avd SD卡空间设置为256MB,但这个错误太相同了
