Crashlytics.getInstance().setListener(new CrashlyticsListener() {
  @Override
  public void crashlyticsDidDetectCrashDuringPrevIoUsExecution() {
    // now it's the right time to show the dialog
  }
});
Crashlytics.start(context);

如果您正在使用新的Fabric集成,则代码略有不同(as seen here).它应该如下所示：

Fabric.with(this,new Crashlytics());
Crashlytics.getInstance().setListener(new CrashlyticsListener() {
  @Override
  public void crashlyticsDidDetectCrashDuringPrevIoUsExecution() {
    // now it's the right time to show the dialog
  }
});

编辑2(最新的Fabric SDK已弃用setMethods)

final CrashlyticsListener listener = new CrashlyticsListener() {
            @Override
            public void crashlyticsDidDetectCrashDuringPrevIoUsExecution(){
                  // now it's the right time to show the dialog
            }
        };

final Crashlyticscore core = new Crashlyticscore
                                  .Builder()
                                  .listener(listener)
                                  .build();

Fabric.with(this,new Crashlytics.Builder().core(core).build());

要测试集成,只需调用Crashlytics.getInstance().crash()即可.简单但方便.
