更新Android Studio 2.2.3之后，我尝试运行的小应用程序在即时运行时一直崩溃。我正在Tecno P5 android 4.2.2版上测试该应用程序
我一直在尝试简单的应用程序，但没有成功。通过这个，我正在尝试一个简单的启动屏幕。
这是logcat:

我的主要 Activity :
package com.example.davy.splash;
import android.content.Intent;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
private static int SPLASH_TIME_OUT = 4000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent homeIntent = new Intent(MainActivity.this,Home.class);
startActivity(homeIntent);
finish();
}
},SPLASH_TIME_OUT);
}
}
最佳答案
在我将V2更改为V1签名之前，我会经历同样的事情。所有应用在Android 4.x设备(SDK API 19)中崩溃。检查您是否正在尝试使用签名版本2或版本1生成签名的APK。APK签名方案v2定位于Android 7.0(API级别24)。如果您将Android 4.x定位为V1 Signature for earlier Android 4-6，请使用版本1
关于android-studio-2.2 - 不幸的是，更新到Android Studio 2.2.3之后，我所有的应用程序都崩溃了，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42425572/
