java - Android 应用程序在调试中工作但不在发布中

Question

我正在将我的第一个程序移植到 android，该应用程序是一个简单的按钮点击器，它将前一个数字加 1 以计算您点击的次数。当我尝试运行代码的发布版本时，当我尝试按下按钮时它崩溃了。我对调试版本没有任何问题。

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

TextView text;
Button adder;
Button reset;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    text = (TextView) findViewById(R.id.text);
    adder = (Button) findViewById(R.id.button01);
    reset = (Button) findViewById(R.id.button02);

}

protected void add(View view)
{
    int count;
    count = Integer.parseInt((String) text.getText()) + 1;
    text.setText("" + count);
}

protected void reset(View v)
{
    text.setText("0");
}

}

这是 XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Click"
    android:onClick="add"
    android:layout_above="@+id/button02"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="59dp" />

<Button android:id="@+id/button02"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="reset"
    android:onClick="reset"
    android:layout_marginBottom="136dp"
    android:layout_alignParentBottom="true"
    android:layout_alignLeft="@+id/button01"
    android:layout_alignStart="@+id/button01" />

<TextView android:id="@+id/text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="0"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="49dp" />

更新:渐变构建

apply plugin: 'com.android.application'

android {
signingConfigs {
    config {
        keyAlias 'austin'
        keyPassword 'Austin42'
        storeFile file('D:/key.jks')
        storePassword 'Austin42'
    }
}
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "austinhenley.clicker"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    multiDexEnabled true
    versionName "1.0"
    signingConfig signingConfigs.config
}
buildTypes {
    release {
        minifyEnabled false
    }
}
productFlavors {
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
wearApp project(':wear')
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:multidex:1.0.1'
testCompile 'junit:junit:4.12'
}

我已经能够在发布版本上运行调试器，这是按下按钮时发生的情况

Answer 1

如果它在调试中工作而不是在发布中工作，则可能是混淆器问题。

检查 build.gradle 文件中的这一行，并确保将其设置为 false

minifyEnabled false

混淆工具中的混淆工具，用于编译的 android apks。但它需要一个规则文件。如果您需要详细解释，请告诉我!
