如何修復Android應用程序崩潰問題？

Question

我在 android studio 上的項目在少數手機和模擬器上運行良好，但在許多手機上崩潰。 我有一個 Main_Activity，點擊登錄會進入第二個活動。 我正在與 android manifest 共享這兩個活動的 java 文件和 xml 文件。

主活動 Java 文件

package club.pithynews.iitbhilai_pithy;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private EditText username;
    private EditText password;
    private Button login_button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        java.text.DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        LoginButton();
    }

    public void LoginButton() {
        username = (EditText) findViewById(R.id.editText);
        password = (EditText) findViewById(R.id.editText2);
        login_button = (Button) findViewById(R.id.button);

        login_button.setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        if ((username.getText().toString().equals("user"))&&(password.getText().toString().equals("pass"))) {
                            Intent intent = new Intent("club.pithynews.iitbhilai_pithy.User");
                            startActivity(intent);
                        }
                    }
                }
        );
    }

Answer 1

錯誤是不言自明的。 您正在嘗試加載過大的圖像。

Canvas: trying to draw too large(111300000bytes) bitmap.

您在ImageButton或ImageView上設置的可繪制源之一太大。 你可以：

• 手動縮放圖像
• 在代碼中執行縮放並在之后設置圖像

Answer 2

java.lang.RuntimeException: Canvas: trying to draw too large(111300000bytes) bitmap.

如您所見，您正在嘗試顯示太大的圖像。 檢查包含的位圖資源的大小。

Answer 3

您正在顯示大小為111.3 mb的圖像，該圖像太大而無法處理，您需要在顯示之前壓縮並縮放到某個較小的版本。 在這里你可以縮放你的圖像。

Bitmap scaled = Bitmap.createScaledBitmap(originalBitmap, 120, 120, false);

在這里更多並使用壓縮

ByteArrayOutputStream out = new ByteArrayOutputStream();
scaledBitmap.compress(Bitmap.CompressFormat.JPEG, 85, out);
