Android 应用程序可在模拟器上运行，但不会安装在我的手机上

Question

我正在自学编写 Android 应用程序，我编写了一个简单的小费计算器作为入门项目。该程序在模拟器上运行良好，但当我导出 apk 文件时，它不会安装在我的手机上。我用 adb 传输了文件，因为 adb 不会检测到该设备。我在 ubuntu 12.04 上，我在 udev 规则中有供应商代码，设备是 Huawei Ascend (M860)我怎样才能找到出错的日志。或者我做错了什么的想法。

这是主要的java文件:

package com.groundscore.gstipcalc;

import android.os.Bundle;
import android.app.Activity;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.Menu;
import android.widget.EditText;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;

public class MainActivity extends Activity {

// Constants used when saving and restoring

private static final String TOTAL_BILL = "TOTAL_BILL";
private static final String CURRENT_TIP = "CURRENT_TIP";
private static final String BILL_WITHOUT_TIP = "BILL_WITHOUT_TIP";

private double billBeforeTip;   // Users bill before tip
private double tipAmount;   // Tip amount
private double finalBill;   // Bill plus Tip

EditText billBeforeTipET;
EditText tipAmountET;
EditText finalBillET;

SeekBar tipSeekBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);// Inflate the GUI

    // Check if app just started, or if it is being restored        
    if(savedInstanceState == null){

        billBeforeTip = 0.0;
        tipAmount = .15;
        finalBill = 0.0;

    } else {
        // App is being restored

        billBeforeTip = savedInstanceState.getDouble(BILL_WITHOUT_TIP);
        tipAmount = savedInstanceState.getDouble(CURRENT_TIP);
        finalBill = savedInstanceState.getDouble(TOTAL_BILL);

    }

    // Initialize the EditTexts

    billBeforeTipET = (EditText) findViewById(R.id.billEditText);
    tipAmountET = (EditText) findViewById(R.id.tipEditText);
    finalBillET = (EditText) findViewById(R.id.finalEditText);

    tipSeekBar = (SeekBar) findViewById(R.id.changeTipSeekBar);

    tipSeekBar.setOnSeekBarChangeListener(tipSeekBarChangeListener);

    billBeforeTipET.addTextChangedListener(billBeforeTipListener);

}

private OnSeekBarChangeListener tipSeekBarChangeListener = new OnSeekBarChangeListener(){

    @Override
    public void onProgressChanged(SeekBar seekBar, int progress,
            boolean fromUser) {

        tipAmount = (tipSeekBar.getProgress()) * .01;

        tipAmountET.setText(String.format("%.02f", tipAmount));

        updateTipAndFinalBill();

    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub

    }


};

private TextWatcher billBeforeTipListener = new TextWatcher(){

    @Override
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub

    }


    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before,
            int count) {
        try{

            billBeforeTip = Double.parseDouble(s.toString());
        }catch(NumberFormatException e){

            billBeforeTip = 0.0;
        }

        updateTipAndFinalBill();

    }


};



private void updateTipAndFinalBill() {

    double tipAmount = Double.parseDouble(tipAmountET.getText().toString());

    double finalBill = billBeforeTip + (billBeforeTip * tipAmount);

    finalBillET.setText(String.format("%.02f", finalBill));
}

protected void onSaveInstanceState(Bundle outState){

    super.onSaveInstanceState(outState);

    outState.putDouble(TOTAL_BILL, finalBill);
    outState.putDouble(CURRENT_TIP, tipAmount);
    outState.putDouble(BILL_WITHOUT_TIP, billBeforeTip);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

这是布局:

Answer 1

我认为您可能使用了“项目右键单击 -> Android 工具 -> 导出未签名 应用程序包”并无意中创建了一个未签名的 APK。未签名的 APK 将不会在模拟器或实际设备上运行。当您从 Eclipse 将应用程序运行到模拟器时，APK 会使用调试证书进行签名，因此通过这种方式 APK 仍会进行签名。

将 APK 传输到您的设备的最快方法是转到目录/bin，那里应该有一个 APK，它会刷新您所做的所有更改并在模拟器上运行更改。
