Question

首先，对不起，英语不好。

伙计们，我有一个带有Minsdk 14和compil / target 22的旧项目。我确实更改为28，以便在Google Play中上传。将java文件中的所有内容更改为AppCompatActivity并导入。但是apk有问题。

代码没有错误，'run'app也没有错误。但是该应用程序无法打开，每次都会出错。

新gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.3"
    compileOptions.encoding = 'windows-1251' //кодировка
    defaultConfig {
        applicationId "com.my.app"
        minSdkVersion 14
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

新的Java示例

package com.my.app;

import android.content.Intent;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
import android.view.View;

public class Activity extends AppCompatActivity implements View.OnClickListener {

老摇篮

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'
    compileOptions.encoding = 'windows-1251' //кодировка
    defaultConfig {
        applicationId "com.my.app"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:support-v4:22.2.0'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile files('libs/Parse-1.9.3.jar')
    compile files('libs/bolts-android-1.2.0.jar')
}

旧的Java示例

package com.my.app;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;


public class Activity extends ActionBarActivity implements View.OnClickListener {

默认情况下，Android 6.0中已删除Apache HTTP客户端。要继续使用它，请将其添加到build.gradle的android { ... }块中：

useLibrary 'org.apache.http.legacy'

有关删除的更多信息，请参见here。
