【问题描述】:
我的代码中不断出现 NoClassDefFoundError。这是代码:
handler.postDelayed(check = new Runnable() {
@Override
public void run() {
if (foreground && paused) {
foreground = false;
Log.i(TAG, "went background");
for (Listener l : listeners) {
try {
l.onBecameBackground();
} catch (Exception exc) {
Log.e(TAG, "Listener threw exception!", exc);
}
}
} else {
Log.i(TAG, "still foreground");
}
}
}
, CHECK_DELAY);
将new Runnable()分配给check时出现错误
我尝试分离Runnable,但没有成功
final Runnable temp = new Runnable() {
@Override
public void run() {
if (foreground && paused) {
foreground = false;
Log.i(TAG, "went background");
for (Listener l : listeners) {
try {
l.onBecameBackground();
} catch (Exception exc) {
Log.e(TAG, "Listener threw exception!", exc);
}
}
} else {
Log.i(TAG, "still foreground");
}
}
};
handler.postDelayed(check = new Runnable() {
@Override
public void run() {
if (foreground && paused) {
foreground = false;
Log.i(TAG, "went background");
for (Listener l : listeners) {
try {
l.onBecameBackground();
} catch (Exception exc) {
Log.e(TAG, "Listener threw exception!", exc);
}
}
} else {
Log.i(TAG, "still foreground");
}
}
}
, CHECK_DELAY);
错误现在出现在final Runnable temp = new Runnable() {行上
发生了什么?我检查编译的类和文件在那里。类和 $ 类。是否有解决方案或替代方案?

【问题讨论】:
-
介意发布错误日志吗?
-
认为定位前景对象是不可行的。
-
发布你的 ForegroundHelper 类代码
-
我使用它,但我将它的精确副本创建到一个名为 ForegroundHelper 的新类中(将 Foreground 引用更改为 ForegroundHelper):gist.github.com/steveliles/11116937
