我的应用程序已在调试版中经过全面测试，并且运行正常。另一方面，发布版本崩溃了。因此，我已采取措施调试发行版本（BuildType Release：debuggable true）。现在我可以看到应用程序调用onCreateView来获取一个段，该段在启动时未加载。在这个onCreateView里面，我一步一步地看到，该程序在另一个函数内部进行了一步（是的，不是在开头，而是在中间的某个地方）。所以我写了＃34;跑狂＆＃34;。
这是我的build.gradle：
apply plugin: 'com.android.application'
android {
signingConfigs {
Signed {
keyAlias 'xxx-certificate'
keyPassword 'aaaaaaaaa'
storeFile file('E:/_Arbeiten/AndroidStudioProjects/KeyStore/xxxKeystore')
storePassword '9999999'
}
}
compileSdkVersion 23
buildToolsVersion "23.0.3"
useLibrary 'org.apache.http.legacy'
defaultConfig {
minSdkVersion 16
targetSdkVersion 22
}
buildTypes {
release {
signingConfig signingConfigs.Signed
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
resValue "string", "test_version", "No"
debuggable true
}
debug {
resValue "string", "test_version", "Yes"
}
}
productFlavors {
German {
applicationId "de.xxx.android.xxxDict.DE"
versionCode 25
versionName "3.0"
}
English {
applicationId "de.xxx.android.xxxDict.EN"
versionCode 25
versionName "3.0"
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile project(':lvl')
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.google.android.gms:play-services:9.4.0'
compile 'com.google.android.gms:play-services-ads:9.4.0'
compile 'com.google.android.gms:play-services-identity:9.4.0'
compile 'com.google.android.gms:play-services-gcm:9.4.0'
compile 'com.google.android.gms:play-services-auth:9.4.0'
}
直到现在我都试过了：
我还重启了Android Studio并多次清理了该项目。问题仍然存在。发布版本绝对无法正常运行。
我知道compileSdkVersion 23不是最新版本，但是如果我使用版本24，我还有很多其他问题。
事实：调试工作正常（签名或未签名） 事实：发布版本在启动时立即崩溃
让某人了解会发生什么？
编辑：在LogCat中，我看到以下内容（Program Malibu）：

请记住我说的话： Programm调用onCreateView，该段不应在开始时加载。这是一个详细视图，稍后在列表中单击后会打开。
当我将我的发布版本调试并在onCreateView上设置断点时，我可以单步直到第32行。下一步进入第78行！这不是很疯狂吗？
这是我的onCreateView（我只添加了两个提到的行号32和78）：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.detailview, container, false);
if (savedInstanceState != null) {
// Restore last state
mIndex = savedInstanceState.getInt("Index");
mLexItemList = savedInstanceState.getParcelableArrayList("List");
}
Bundle bundle = this.getArguments();
wv = (WebView) v.findViewById(R.id.webView);
btnSpeaker = (ImageButton) v.findViewById(R.id.btnSpeaker);
btnSpeaker.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (mIndex < mLexItemList.size()) {
btnSpeaker.setImageResource(R.drawable.speaker_i);
btnSpeaker.setEnabled(false);
mLexItemList.get(mIndex).Sprechen(onSprechenFertig);
}
}
});
btnSpeaker.setImageResource(R.drawable.speaker_i);
btnSpeaker.setEnabled(false);
btnMemo = (Button) v.findViewById(R.id.btnMemo);
btnMemo.setEnabled(false);
btnNext = (ImageButton) v.findViewById(R.id.btnNext);
btnNext.setEnabled(false);
btnBack = (ImageButton) v.findViewById(R.id.btnBack);
btnBack.setEnabled(false);
if (bundle != null) {
32 if (bundle.getInt("Memo", 0) == 1) {
btnMemo.setEnabled(true);
btnMemo.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String suchwort;
int setSound=0;
LexItem lexItem = mLexItemList.get(mIndex);
HistoryDatabase db = new HistoryDatabase(getActivity());
if (mSuchwort.equals(""))
suchwort = lexItem.getThai();
else
suchwort = mSuchwort;
if (suchwort.substring(0, 2).equals("* ")) {
suchwort = suchwort.substring(2);
} else if (suchwort.substring(0, 2).equals("+ ")) {
suchwort = suchwort.substring(2);
}
String lang = "";
switch (lexItem.getLexTyp()) {
case ltDeutschThai: lang = "Text"; break;
case ltThaiDeutsch: lang = "Thai"; break;
case ltThaiumschriftDeutsch: lang = "Trans"; break;
}
String detail = lexItem.getBeschreibung();
if (detail.indexOf("*:;") > 0)
setSound++;
if ((detail.substring(0, 1).equals("*")) | (detail.substring(0, 1).equals("+"))) {
detail = detail.substring(1);
}
db.saveHistory(-1, lang, suchwort, lexItem.getThai(), lexItem.getLautschriftRoh(),
detail, lexItem.getVoicedatei(), setSound);
Toast t = Toast.makeText(getActivity(), R.string.memosave, Toast.LENGTH_LONG );
t.show();
}
});
}
if (mLexItemList.size() > 1) {
if (bundle.getInt("Next", 0) == 1) {
btnNext.setEnabled(true);
btnNext.setImageResource(R.drawable.btn_next_a);
btnNext.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (mIndex < mLexItemList.size() - 1) {
78 mIndex++;
refreshView();
setSelection(mIndex);
}
}
});
}
if (bundle.getInt("Back", 0) == 1) {
btnBack.setEnabled(true);
btnNext.setImageResource(R.drawable.btn_previous_a);
btnBack.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (mIndex > 0) {
mIndex--;
refreshView();
setSelection(mIndex);
}
}
});
}
}
}
return v;
}
再次：此问题仅在发布版本上，而不是在调试版本中！因此代码必须正常，问题可能在gradle中？
