我有一个奇怪的问题.我构建了一个在调试模式下运行良好的应用程序(直接调试到我的手机并在我的手机上安装了调试 APK)但是如果我使用发布版本 APK，该应用程序会在某一时刻崩溃.我发现应用在发布 APK 时崩溃，但我不知道为什么以及我能做什么:

I have a curious issue. I built an app that works fine in debug mode (direkt debugging to my phone and with debug APK installed on my phone) but the app crashes at one point if I use the release build APK. I found the point where the app crashes with release APK, but I don't know why and what I can do:

protected final String TABLE = "done";
protected final String COL_ID = "_id";
protected final String COL_TASK = "taskid";
protected final String COL_DATE = "donedate";

protected String getLastDoneDate(String id) {
    String date = "";

    String filter = COL_TASK + " LIKE ?";
    String[] filterArgs = new String[] {id};
    String sortOrder = COL_DATE + " DESC";
    String[] columns = new String[] {COL_DATE};
    Cursor c = MyTime.db.query(TABLE, columns, filter, filterArgs, null, null, sortOrder, "1");
    if (c.moveToFirst()) {
        date = c.getString(c.getColumnIndex(COL_DATE));
    }
    c.close();

    return date;
}

如果我删除 Cursor c = ... (以及所有根据 c)行，它就可以工作.

If I remove the line Cursor c = ... (and all according to c) it works.

数据库看起来像这样:

CREATE TABLE IF NOT EXISTS done (
                _id INTEGER PRIMARY KEY autoincrement,
                taskid INTEGER,
                donedate TEXT DEFAULT '');

Gradle 代码段:

Gradle Snippet:

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

我无法调试发现问题，因为调试时不会发生崩溃.

I can not debug to find the problem because the crash does'nt happen while debugging.

有人可以帮我解决这个问题吗?

Can somebody help me to solve this issue?

推荐答案

我在 gradle 文件中添加了 debuggable = true 并找到了问题的原因.

I added debuggable = true to my gradle file and found the reason of my problem.

buildTypes {
release {
    shrinkResources false
    debuggable true
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
    shrinkResources false
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}

未创建表完成"，因为我试图将两个表创建语句放入单个 db.execSQL()

Table "done" was not created because I tried to put two table create statements into a single db.execSQL()
