[英]I can run my emulator(Android studio) but in emulator screen I can't find the app I made
[英]I am unable to view my app on the android studio emulator screen
我無法在android studio模擬器屏幕上查看我的應用。 我嘗試使用GPU主機,增加的Ram,固定的HAXM,固定的VT-X。 我認為問題可能出在我的代碼上。 由於我是Android和Java的新手。 我還將包括java文件和xml文件。 我嘗試重新啟動,從而降低了API級別。 android logcat也已附上。 這個應用程式嘗試將兩個數字相加。
Java代碼:
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.os.PersistableBundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends ActionBarActivity{
Button add;
TextView ans;
EditText n1, n2;
@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
setContentView(R.layout.activity_main);
add = (Button) findViewById(R.id.button1);
ans = (TextView) findViewById(R.id.textView1);
n1 = (EditText) findViewById(R.id.editText1);
n2 = (EditText) findViewById(R.id.editText2);
add.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int a,b,c;
a = Integer.parseInt(n1.getText().toString());
b = Integer.parseInt(n2.getText().toString());
c = a+b;
ans.setText(""+c);
}
});
}
}
xml代碼:

您需要確保擁有必需的ARM EABI v7a系統映像和目標API的Android SDK 。 例如,如果您正在為API 15開發應用程序,則需要檢查是否具有API 15的系統映像和SDK。
