Android应用程序可在模拟器上运行，但无法安装在我的手机上

Question

I am teaching myself to program android apps, i wrote a simple tip calculator as a starter project. The program runs fine on the emulator, but when i export an apk file it wont install on my phone. i transferred the file with out adb because adb wont detect the device. i am on ubuntu 12.04, i have the vendor code in udev rules, the device is Huawei Ascend (M860) how can i find a log of what went wrong. or an idea of what i did wrong.

this is the main java file:

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;
    }

}

this is the layout:

Answer 1

I think you may have used "Project Right Click -> Android Tools -> Export Unsigned Application Package" and inadvertently created an unsigned APK. Unsigned APKs will not run on neither the emulator nor actual device. When you run the app from Eclipse to an emulator, the APK is signed with a debug certificate, so in this way the APK is still signed.

The fastest way to get an APK to be transfer to your device would be go to dir /bin, there should be an APK there which is refreshed everything you've changed something AND has run the changes on the emulator.

Answer 2

Your phone appears on the devices list??

For you know, go to your adb installation and run the adb tool

you_path\\adt-bundle-windows-x86_64\\sdk\\platform-tools

adb devices

This should list your devices connected to your tool.

Make sure the emulator is down.

Answer 3

May be , There will be a problem in your minSdkVersion , targetSdkVersion !

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

minSdkVersion="8" : for android 2.3

targetSdkVersion = "17" for android 4.1

your phone is Lower SDK , and your .apk file is created with Higher SDK .
